Why MOSFET heats up and blows up at 50 kHz boost converter?
it looks like the inductance of the coil is too small to limit the current at such an operating frequency. It is necessary either to increase the frequency of operation of the converter or to increase ...

Why MOSFET heats up and blows up at 50 kHz boost converter?
This green core isn’t suitable for energy accumulation. It’s more for noise canceling when used as common mode choke.
The current through coil probably rises
to extreme values so a huge current flows ...

Why MOSFET heats up and blows up at 50 kHz boost converter?
Made with microcap v12
To show the behavior, I simulated this circuit.
This show that a "controller" should be used to limit the current into the MOSFET.
Otherwise, the MOSFET is burned at ...

Very high speed counter (around 1.5 GHz to 2 GHz)
Here's another idea: Frequency Modulated Continuous Wave radar
Ramp the tx waveform frequency over some bandwidth.
Replace the echo source with a passive retroreflector
Mix the received wave with the ...

Board-to-Board high current pin header for planar PCB winding
Solution 1:
Install broaching PCB PEM nuts on each hole Pick ones whose thickness results in the desired spacing between boards
Stack the boards
Insert a long screw from the top with a smaller ...

What am I misunderstanding in the derivation of skin depth?
Amazingly, different boundary conditions lead to different field configurations. :)
Ok, not to get too flippant or anything... but, to say: the missing insight is about what fields and geometry are ...

This PCB from doppler radar from car to detect blind angles how are these traces made?
How were these traces made?
That is a printed circuit board. Some substrate (here, some RF ceramic) got coated with copper, then a photosensitive lacquer was applied.
Then, the lacquer was exposed ...
