The first real board I made here was the most advanced one I did, (18L, blind/buried vias) since then, like 4 years ago, itβs been not career-advancing stuff

One more to go!
10 MHz - 6 GHz RF front end board
Local oscillators and FPGA clock board
Base board where four RF boards, one clock board, and one FPGA SOM plug into. Provides power and IO between PCBs.
Castellated baseband filter board, so it can be revised without respinning the entire RF board.
Now we wait for fabs to arrive π€
