[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...
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,...
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...
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...
he 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...
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...
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,...
We have gone over NanoVNA so many times in the past. I did a complete review of the inexpensive NanoVNA last month. Furthermore, I compared it with the super-expensive Keysight N9952A Vector Network Analyzer....
There are so many new RF devices coming out these days which has pushed the envelope the technology where a common person can access it. In one of the previous posts, I demonstrated how...
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...
