Hello,
I'm using the Smith chart on a VNA to determine the matching circuit for my PCB (an RF switch (LoRa, WiFi and GNSS) and an antenna (NN02-224)). I found the matching networks for GNSS and LoRa using theory, and the VNA shows good results.
However, for WiFi, I couldn't get a good match...
Hi folks,
I'm thinking of getting a nano vna to measure the S-Parameters of RF transistors. One thing I noticed is that I've only seen the magnitude expressed in dB. I'm used to it expressed in absolute value of the magnitude.
How do I set the instrument to read the absolute value of...
I've searched the Web, but I can find no mention of using a common USB antenna analyzer (such as the Mini60/SARK-100 with software) to graph the band-pass of an HF filter. To me, it seems like a no-brainer, but perhaps I'm missing something critical here:
Antenna analyzer-->LPF/HPF/BPF...
