A simple HF up converter with LimeSDR
In times like these when we are all stuck in our homes, most of us are becoming active on the radio. The best ideas come out when we are challenged and right now we...

Programming the Zynq 7000 with Vivado 2019.2 and Vitis
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...
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...
Constructing an X-Band power amplifier with FMM5061VF
[s2If current_user_can(access_s2member_level1)] As we go up in the frequency range, things start getting tricky. The discretely available capacitors start to behave like inductors. On the other hand, even a couple of millimetre long length...
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,...
NEJE DK-BL 1500 laser engraving tool review
Laser engraving can be a fun pass time. If you often create art, a laser engraving machine can help you put that design onto a piece of wood or cardboard. Burning your artwork on...
Race to the bottom – A comparison of PCBWay and JLCPCB circuit boards in 2019
Making circuit boards used to be an expensive affair several years ago. Today, you can have a bunch of 2 layer or even 4 layer PCB done for less than $30. Thanks to the...
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...
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...
Building an automatic gain control (AGC) circuit
Most amplifiers we use have a fixed gain. In case of excess input power, the amplifier saturates. As a result, the blocks down the receive chain also get affected by this. To avoid this,...
