Transmitting SSB audio with LimeSDR Mini
There are so many new RF devices coming out these days which has pushed the envelope the technology where a common person can access it. In one of the previous posts, I demonstrated how...

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...
Manual VCO selection for a faster locking PLL
PLL chips such as the ADF43xx, MAX287x and so on come with an integrated VCO. The frequency range on these PLL chips can extend all the way from few tens of MegaHertz to several...
RF Pulse generation with RF switch
Remember the previous post where we generated PWM? We are going to use the PWM output from the TivaC microcontroller and drive an RF switch. I will be using the Minicircuits HSWA2-63DR+ SP2T switch...
Getting LimeSDR Mini to work for the first time
LimeSDR is a real temptation to buy if you are an RF or a signal processing guy. We all know FPGAs give you a huge set of building blocks of the digital world and...
