Easy to use AD9833 C Library
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...
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...
Using the Signal Integrity tool in Altium Designer – Part 1
Our designs are becoming faster to serve our ever-growing demands from machines. Speed brings more complexity to the design. The usual slow transitions from 0 to 1 and 1 to 0 become so fast...
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...
Receiving with 2 channels on PlutoSDR
The Analog devices PlutoSDR comes with the AD9361 chip. Meant for learning, the PlutoSDR comes at a much more affordable cost as compared to the USRP. Of course, the USRP has its own advantages...
Why ‘PPM’ matters in the GHz bands!
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...
Reviewing the new NanoVNA v2 (SAA-2) – Part 2
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...
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...
