Reviewing the new NanoVNA v2 (SAA-2) – Part 1
The first version of NanoVNA became an instant hit for very obvious reasons. First, it was offering stunning performance. Second, a super low price which brought VNA into the hands of those who would...
Make your own Phased Matched cables with NanoVNA
Phase matched cables come handy when dealing with phasing elements of an antenna or even when you want to deliver differential signals. There was a time when making phase matched cables meant use of...
Cable impedance profile with NanoVNA and TDR script
We have gone over NanoVNA so many times in the past. I did a complete review of the inexpensive NanoVNA last month. Furthermore, I compared it with the super-expensive Keysight N9952A Vector Network Analyzer....
Accurately measuring cable length with NanoVNA
Update: Now you can plot the impedance vs. distance/time plot. Click here to learn the concept. Original Post: Having a VNA opens up so many possibilities. Just last week, I reviewed the nanoVNA and...
Comparing NanoVNA with the Keysight Fieldfox N9952A
Vector network analysers (VNA) come in all sort of price ranges. Most of them are out of reach for a typical hobbyist. Very few VNAs are available to be bought by someone like you...
NanoVNA – A short review
Do you build RF circuits? Have you built any antennas? If the answer to any of the two questions is YES, then you know how valuable having a VNA (Vector Network Analyzer) is. Just...
Transmit channel phase shifting on PlutoSDR
The PlutoSDR Rev C brings out both the transmit and receive channels. Thus, making it an even more capable device, especially for advanced RF stuff. A phased array is an advanced RF application that...
Noise Figure measurement with TinySA Ultra
In an article I wrote long time ago, I measured the noise figure of an amplifier using only a spectrum analyzer. The method I used was relatively simple but it took some mathematical understanding...
Quickly designing a 23cm Hairpin filter in ADS
A 23cm hairpin filter operates around the 1.296GHz amateur radio band. The frequency being low enough allows us to fabricate it on a low cost FR4 substrate. It operates as a bandpass filter. There...
