Congratulations, you have found one of the most useful areas of the Microwaves101 site! Here are some calculators that will help you in your microwave work. Check back often, we plan to continuously add more! If you notice any errors or have problems with a Microwaves101 calculator, let us know and we will do our best to fix it. And if there is something in the microwave universe that you need to calculate often, drop us a note and we'll see what we can do to include it here. You may win a fine Microwaves101 pocket knife for your suggestions!

Be sure to check our download area for stuff we couldn't fit into a simple HTML calculator. Right now we have Excel spreadsheets for:

Synthesizing lumped-element Chebyshev filters (N=3, N=4 and N=5),

Calculating RF sheet resistance for up to three metal layers,

Calculating N-section impedance transformers,

Calculating and plotting group delay from S-parameters,

Calculating and plotting K-factor and maximum available gain from S-parameters (our famous S-Parameter Utilities spreadsheet!)

Cascade analysis of gain, P1dB and noise figure

and more!

There might be one or two links to calculators on our Cool Links page.
