![]() ![]() They inherited it from Agilent, who inherited it from Hewlett Packard, who bought eeSOF way back in the 1990s. ![]() Keysight is now the copyright holder of the word Touchstone, when it is used in this context. Long ago a company called eeSOF came up with a standardized way to express S-parameters in a text file which is often referred to as a Touchstone® file. It is explained on our page on Fourier's Law.ĭownload Transient_heat_analysis_M101_Rev-.xlsx ![]() It's a big file, as it is performing numerical integration in two dimensions (distance and time). Here is an Excel file that analyzes transient flow in one dimension. There's even a graphic included!ĭownload the Antenna range calculator spreadsheet Here's a spreadsheet from our friends over at Texas Instruments that will help you estimate antenna range using the Friis-Equation and 2-Ray Ground Reflection Model. There are two PDF files, make sure you grab them both.ĭownload the Stability Analysis appendices For more information, we offer a page on NDF here. Here are two presentations contributed by Wayne Struble on Normalized Determinate Function, the Cadillac of stability analyses. Here's the TRL calculator we promised you over on our TRL calibration page. And here is the accompanying spreadsheet:ĭownload the capacitor dissipation spreadsheet It is explained here.ĭownload the S-parameter mixer spreadsheetĭownload the H-tree feed network spreadsheetĬharge storage capacitor dissipation is described on this page. New for January 2021! This tool allows you to shift the frequency of an IF amplifier's S-parameters so you can cascade it with your RF chain in a receiver design. July 2021:This calculator comes from Ticer - thanks, guys! The spreadsheets below supplement our calculator page, and in general offer data-crunching that is too complicated to put onto an HTML page for you. Here are three waveguide-related spreadsheets from XXX Here is a skin-depth spreadsheet, contributed by Chris (thanks!!) Thanks, Paul!Īnd the paper that describes the derivation of the group velocity, group delay, and parabolic phase shift formulas in the group delay spreadsheetĭownload a spreadsheet of thermal resistance calculationsĪnd the paper that describes the derivation of the thermal resistance formulasĭownload a spreadsheet for theoretical attenuation calculations He's provided spreadsheets that do the calculations for you, and also document files (in PDF) that describe the derivations of some of the formulas he used. Paul Chorney, an expert in all things waveguide. ![]() Let us know what improvements you'd like to see!ĭownload the pulsed RF spectrum spreadsheet It is pretty basic, but allows you to plot RF spectrum based on center frequency, CW power, pulse with and duty cycle. New for April 2023: here is a pulsed RF spectrum spreadsheet, that goes along with this Microwaves101 page. matching_network.py - Program written for Python.ĭownload matching with lumped elements (Zip file) Spreadsheet and text downloads matching_network.cpp - Source C++ code for the "matching_network.exe",ĥ. matching_network.exe - Executable (stand-alone) program,Ĥ. matching_network.m - Program written for Octave/Matlab,ģ. Matching with lumped elements.pdf - Relatively short text with some theory, few examples, and programs description,Ģ. There calculator is embedded in a zip file, which contains:ġ. Beware, you need to enter the frequency in Hz, not GHz. The networks could be referred to as high-pass and low-pass networks. You can find it in our download area (look for "Matching with lumped elements.zip) For a given complex impedance and center frequency, it provides two different L-section transformations to your choice of (real) characteristic impedance. New for March 2023. We now offer a lumped-element matching calculator, thanks to Antonije and Slobodan at University of Belgrade. We offer a Microwave Office (MWO) file on symmetric three-section coupler designs, which was used to generate the content on this page.ĭownload the three section symmetric coupler design file for Microwave Office. You can load your own 3dB hydrid coupler four-port S-parameters into it and determine overall loss and other parameters.ĭownload the Microwave Office combiner loss project Here's a Microwave Office project that calculates full combiner loss, explained on this page (new for August 2021). Under this category offer example files in environments such as Keysight ADS, AWR Microwave Office, HFSS, etc. Information downloads Electronic design analysis (EDA) projects Our download area is divided into five categories:Įlectronic design analysis (EDA) projects Welcome to our Microwaves101's Download Area!
