Mixer pcb, AMP pcb and MO pcb are the same with that in scotty’s SA project.
The AMP board uses an ERA-3SM and an ATF35176 which can work to 18GHz. It is sufficient for most SAs.
A 10.000MHz crystal oscillator is installed on the MO board which provides reference to both “tracking generator” and “SA”.
Mixer board is a general one, where most mixers of mini-circuits can be mounted on, e.g., RMS-42, ADE-11x etc.
