Apollo Microwaves Exposed
There is a series starting on YouTube examining some of the RF electronics used in the 1960’s Apollo space program.
There is a TWT PA module and a transponder module installed in the command module that are to be investigated.
This will be real RF design, no sending an order to MiniCircuits and mounting all the parts on a PCB.
The system was used to provide communications, telemetry and an active radar for speed and direction all at S band.
They even provided a morse facility as a backup.
I suspect that there were many amateurs involved in the design of this system.
I can just imagine the QC procedure for checking the torque of all the SMA connectors on the transponder assembly.
The group doing the expose intend to open the modules to show what’s inside and then to power the complete system
up and send some real signals through it.
