Testing MRFE6VP61K25H
Photos and video (RU)
Big HF load
It’s based on a copper plate, big old whipped aluminium radiator and two 100Ohm resistors, 800watt each.
Check losses in big LPF
Not good at all — heater

Small things.
Water pump for mrfx1k80: RD16 kit: Optical encoder for wolf: Had an issue with it. Seller mentions that it works with 5-24v
Photos of soldering water blocks to the copper plate
2 U-channel blocks: Soldering paste: With bottom preheater We need to cook: Nasty flux and solder stains: A bit polishing: More:
Amp. control board from 60dbm
STM32 based controller.
Finally — finished big LPF
1.2KW LPF
High pass filter for the LPF for MRFX1K80
My LPF board contains hight pass filter to split harmonics to the 50Ohm load, instead of returning it to the transistor. Measurements.
