rf and microwave

My neighbor passed away a few years back the person that took over his estate gave me this piece of equipment. I’m not sure what it is and what it is used for. jW

There needs to be an RF antenna and detector on the PCB that can detect signals from 8GHz to 40GHz. How can I do it?

Hi everyone, I'm working on an RF project that requires precise calculations for frequency, wavelength, power, and impedance matching. Does anyone have recommendations for a good RF calculator (online tool, software, or spreadsheet)? Are there any open-source tools that you use for RF...

Hello all, I am a newbie in RF a micro strip design. I have some few questions on a design I've received from a friend. I will like to understand the circuit and propose and equivalent with RLC for this circuit. It is a microstrip line consisting of interdigitated lines as shown in the attached...

Hi there (long time reader, first time poster), I'm using an oscilloscope to measure a weak 100 kHz RF burst (at the (1-10)mV scale) with an oscilloscope (externally triggered on the event of the burst). I then take the trace and FFT on MATLAB to get SNR. My issue is with the noise floor...

Hi! I am relatively new to the world of RF design. I am searching for an L-band splitter/combiner that is active and has the ability to inject DC power for a BUC and LNB. I also need 10MHz pass for the TX combiner. I have done a google search to see what is out there in terms of products, but...

Please see attached figure for a few of the questions. I would love for the solutions to these questions. Also, what are the effects when the width of the microstrip line is increased?
