AWR Microwave Office v. I am using the software for research, good work! Boosting productivity of my team by allowing them to input ideas and get the response from other Good software. I absolutely love this. Keep updated! I like the valuable software you provide in your site. I will bookmark your site and check again When I initially commented I clicked the "Notify me when new comments are added" checkbox and now You're so awesome!
I don't believe I've truly read something like this before. So good to I have been surfing online greater than 3 hours as of late, yet I by no means discovered any Related Searches perfect office icons vipnet office for usa on sale edraw office viewer component mini acrobat to office powerpoint converter easy office recovery over the range microwave oventheme maker otr microwave oven twitter tool office recovery tool office firefox theme massage office professional.
Softros Systems, Inc. Spider Financial Corp VB. If you also can not install it or any problems, please contact to me by email: [email protected] , then I will help you to install software by teamviewer. Thanks a lot. Layout editing capabilities have also been added, along with simplified multi-technology management.
Version 13 also addresses specific system requirements with accurate simulated RF front-end component measurements provided through communication libraries for 5G candidate modulation waveforms and phased-array behavioural model enhancements. RF power amplifier designers can now use the system-level load-pull analysis in VSS to generate contours for communication performance metrics such as adjacent channel power ratio ACPR and error vector magnitude EVM.
If you keep reading down this page, we have at least one one other spur table download. Collect 'em all! This is a good example of using ABCD parameters and complex math in a spreadsheet.
This spreadsheet was tuned up during March , now it does multi-bit calculations all at once, and the broken plot was fixed. Download the HP-LP phase shifter spreadsheet. Here's a link budget calculator from Andre. He supplies this spreadsheet to engineers considering point-to-point wireless connections.
OK, this is practically a free advertisement for Adtran, so when you contact them, tell them you found them through this web site and that maybe they should cough up for a sponsorship or we'll remove the link budget calculator one of these days! Here's a freespace path loss calculator contributed by Robert! It is something he put together for coworkers so they could understand Wi-Fi a little better.
It allows you to customize the general RF situation in the environment allowing you to match real world better to estimations. It also allows you to select different frequency ranges.
This is an Excel file, software which we don't have, so we have yet to try it! If anyone has any comments of suggestions we will relay them to Robert.
Note that the file is zipped, we had to do this because most web browsers won't know what to do with an "xlsx" file! Download Robert's Freespace Path Loss calculator. Here a spreadsheet for analyzing even and odd mode impedances of coupled-line couplers.
We now have a multi-section Wilkinson power divider tool for Excel. It is hopefully described in detail on this page. It will analyze up to eight sections but is limited to equal split. The transmission line sections are based on Chebyshev equal-ripple transformer calculations and are exact for the bandwidth that you specify. The resistor calculations are not perfected yet so you might not get the best possible isolation without optimizing the resistors on your own. Be sure to "enable macros" when you open it, and you might have to enable the "analysis tookpaks" to get it to work look under "tools", "add-ins" Here's a "reverse microstrip calculator" a spreadsheet that lets you specify impedance and solves for line width.
It uses linear interpolation , and is explained on this page. Download the reverse microstrip calculator. Here's a simple spreadsheet that will help you understand the concept of frequency translators.
I enjoy Microwaves far too much to be considered normal. Accordingly, the enclosed utility might spark some interest on the subject of VNA calibration fundamentals in some other kindred spirit. I can't imagine another forum that would possibly have any interest at all Please follow up with some text explaining the spreadsheet and we'll post a page with an example Here's a spreadsheet from Chip that simulates the Klopfenstein taper.
We made it more usable, with 21 impedance steps. We're working on an explanation on this page. Download the Klopfenstein taper spreadsheet. Thanks to David, the spreadsheet below now has a correction to the math which was published by Kajfez and Prewitt in David also made other improvements to make the spreadsheet more usable.
Thanks again! It's all explained on our FraudoCad page. This Excel spreadsheet calculates free space loss and and Fresnel zone radii. Inputs are frequency in GHz, transmitter TPO, antenna gain, transmission line loss, path distance, RX threshold, and obstruction distance for the Fresnel radius.
Outputs are freespace loss in dBm, RX signal in dBm, RX fade margin, 1st, 2nd, 3rd and 4th Fresnel zone radii at the obstruction calc point. We've finally got around to dressing up our VSWR spreadsheet into something we're proud of! After a couple of iterations, we're now at Rev 4. We fixed the math, and added a slider bar so you can animate the waveforms. Note: you have to enable macros in order to get this spreadsheet to work! This spreadsheet has its own page of instructions located here.
Here's a spreadsheet that shows you how to do linear interpolation in Excel, a valuable skill in any engineering field. Here's a page that describes this calculation. Here's a spreadsheet contributed by Harald that shows you how to access the polynomial curve fitting capabilities of Excel! Here's Harald's description of its capabilities:. Everybody knows that you can produce a graph and add a polyline to it.
But do you know, that you also can calculate the coefficients for a polynomial in Excel from a set of data and use them in your spreadsheet directly?
You also can display the function of this polyline in the graph. You can copy and paste this formula into a cell for further use in the spreadsheet. It works, but you have only the accuracy as displayed in the graph and it is a lot of work. I did that until a coworker came up and said there is a simpler way to do it without creating a graph and the copy and paste work. This function is very well hidden in Excel and not easy to find. I created an example spreadsheet to show how it works.
Up to which order of polynomial it works, I have not tried out yet. The benefit of this function is, that you have the full accuracy of Excel for each coefficient, this is especially important for higher orders of polynomials. Here's an RF unit converter from Frank. It's an executable file that converts watts to dB-stuff and voltages, and more. Below is a screen capture that illustrates the capabilities:.
We have a new page that offers some free downloads courtesy of the U. We've only posted the topics that have to do with microwaves, radar and radio, but if there's enough interest we might upload the entire set. You can find these training manuals on many other web sites, but few have the bandwidth that we have for rapid downloads. Some lesser web sites even try to sell them! Thanks to Steve for suggesting this idea! The previous version was missing a couple of curves. We've created a bare-bones Smith Chart using equations for circles inside an Excel file.
Then we stripped away the equations and left just the data. You can use this file any way you like, to plot data on the Smith Chart inside Excel. We'll be using it on some future spreadsheets, you betcha. Here's Kire's level diagram spreadsheet. Kire is one of our best "answerers" on the Microwaves message board, he's a prime example of what makes this a great web site.
However, to draw a miter in AutoCAD with these dimensions can get tedious with the keystroke entry of perpendiculars, offsets, and trim commands, etc. This will quickly let you put the optimum miter on any arbitrary angle from 0 to 90 degrees and you can just click-click-click your way through any bend. The table below the calculator just takes the equation and fills in a variety of widths and angles.
Pardon the minimal graphics, I made this not as a full self-explanatory file, but just something simple to give our CAD guys to speed up their work. Feel free to use or modify any of it, but this only works for AutoCAD.
Other tools use a different method for calculating miters. Here's a spreadsheet that analyzes coupled-line couplers. You can vary the coupling factor, then see what an ideal coupler does over frequency. Be sure to turn on Excel's Analysis Toolpak! Here's a spreadsheet that will help you floorplan a power amplifier! It is described on this page. Download the power amp designer spreadsheet.
Here's a spreadsheet that calculates resistor values for minimum loss L-pads which are described here :. Here's the start of a spreadsheet that looks at the array factor for phased array antenna calculations. Well, OK, it only looks at a single line of antennas from 1 to , it would be too big to download if it simulated an entire array in two dimensions.
It is far from finished, but maybe some smart person out there can take over for us and put some more effort into it. It is useful for looking at the various tradeoffs of gain versus number of elements, grating lobes as a function of element spacing, number of phase shifter bits, type of phase shifter, and a few other things. Feedback is appreciated! Here's two contributions from Spinner GmbH, on waveguide cross sections including ordinary, reduced height, circular and double-ridged and waveguide flange dimensions, both in pdf documents.
These are the most comprehensive lists we have seen so far. As always, thanks to both of you! For January , our waveguide loss spreadsheet has been improved in several ways. We added standard rectangular waveguide all the way to WR0. All the low frequency guides are still in the spreadsheet of course, and you can even make custom cross-sections.
We made it much simpler to generate your own comparison plots, the plot starts with ten different species of guide but you can add or delete lines as required. Enjoy the improved file and make custom versions of the plot below! Here's a table that is more complete than the other one we had on our waveguide dimensions page. It was contributed by Alan D. It has the three primary official designations along with some commercial designations, and interior dimensions are given in millimeters and inches.
Major update June we went through the coax spreadsheet with a fine-toothed comb and found a number of problems, especially with the surface roughness effect on loss. We fixed everything we spotted, and added the ability to plot coax loss versus temperature at three temperatures you choose. Please delete all prior versions if you have stored them. Our spreadsheet performs the exact calculation of metal losses of coax with frequency splitting out the calculations for center and outer conductors.
It also computes dielectric losses due to loss tangent and dielectric conductivity and a ton of other parameters like characteristic impedance, capacitance and inductance per unit length, cutoff frequency, etc.
The spreadsheet handles the offset coax calculation. Our coax calculator is a perfect example of how we wanted Microwaves to work. With the help of our loyal viewers, we've been fixing and updating the spreadsheet and are now up to version 4A. Most recently, Bob pointed out an error on the single frequency point calculation. That's been fixed, and we made the length units include inches, feet, mm and meters.
In prior versions, we fixed a bug in our coax calculator spreadsheet, as pointed out by Joe, and thanks to Sergio from Italy, added surface roughness to the calculation, a topic that we all need to better understand Here's a multi-dielectric coax calculator, contributed by Alex R. We recently corrected a problem with the cut-off frequency calculation for single dielectric, which was pointed out by Andrew thanks!
It will calculate characteristic impedance of coax that contains up to five concentric dielectrics! Be sure to check out our page that explains the math. Download the multi-dielectric coax spreadsheet. Here's a filter calculator from Vlad, which does lumped element calculations Chebyshev and Butterworth and is very cool and admittedly better than the Excel calculator that we offer farther down the page.
We now have a page that describes how to operate Vlad's calculator but it's so simple you could figure most of it out yourself. We've had a lot of positive feedback about this calculator. The latest version offers the uses control over the plot axes. Please send us your comments on this calculator, Vlad volunteers to fix any problems you have! Contributed by Itzik! Our S-parameter Utilities spreadsheet is the ultimate tool for manipulating S-parameters into all manner of plots, including group delay, K-factor, maximum available gain, VSWR, mismatch loss, loss factor, and input and output impedance plots.
You can now quickly plot all of these parameters, from any manufacturers' S-parameters that you can download! We recently added the ability to calculate length of a transmission line if Keffective is known , or velocity factor and Keffective if length is known.
