PipelineC brings HLS to non-Xilinx FPGAs

Those of you who have used HLS (High level synthesis) would know how powerful the thing is. For those of you having some experience working with hardware description languages would most likely be able to write good HLS code. This new method isn’t something where

Measuring noise figure using Gain Method

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 how much noise, for example, your amplifier is adding to the

EM simulation over a PCB designed by you

Doing electromagnetic simulations on your PCB layout can be a difficult task. The main reason being the tremendous effort required in porting your PCB layout data over to the 3D EM simulation software. Fortunately, new updates to the EM solver tools have made our work

Radar Beamforming to track target

The Matlab phased array toolbox is a collection of many interesting algorithms and functions. With so many tools at your disposal, the phased array toolbox lets us build a complete end to end radar system. I tried the phased array toolbox for the first time

Transferring a text file over the air with LimeSDR mini

We have seen the LimeSDR mini several times on this blog. So far, we have only seen how it can generate analog modulation to transmit voice and what not. Being an SDR capable to transmit practically anything, we can even transmit binary data. Speaking of

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 found to be an interesting device to have. Having handled expensive

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 an year ago the cheapest VNA on the market was the
