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...

Hey there, fellow electronics enthusiasts! If you’ve ever tinkered with the signal generation, you’ve likely come across the AD9833 waveform generator chip. But did you know that this little gem can do so much...
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...
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...
In this quick article, I show step by step process of drawing a boost converter schematic and finally ending up with a PCB layout. All of it done on Altium designer using Altium’s own...
An uninterruptible power supply (also called UPS) is a very complex unit that is used for protecting certain devices from power spikes, power outages, while also offering backup capabilities, a backup battery in our...
In the part 1, we reviewed the hardware aspects of the NanoVNA v2 SAA 2. Here, we will review the actual functionality of the device. Those familiar with the NanoVNA v1 need no guidance...
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...
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...
I purchased a Zynq 7000 development board recently and wanted to play with it for quite some time now. Finally, the lock-down due to the corona virus pandemic gave me some time to put...
