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...

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...
Right back in the year 2011, the last blocks of the IPv4 address space were allocated. There were no new blocks left for any future expansion of the IPv4 address. This happened because more...
This is going to be a small tutorial that will allow you to run your GNU Radio script automatically at system boot. I am using a Raspberry Pi 4, a Pluto SDR and GNU...
No matter what frequency you work on, a term called “ppm” always follows. Whether you deal with the good old HF band or you work at the Gigahertz band, “ppm” defines how accurate your...
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...
For those into radio astronomy would know the significance of having ultra-low noise figures. Lower the noise figure, the more sensitive your receiver becomes. Noise figure is a unit of measure that tells us...
