RF Multiplexer 8ch 1GHz
Project Description
This is a PCB-design + Arduino firmware for an Ethernet-controlled 1:8
RF-multiplexer. It allows selecting as output one of eight
input-channels, as commonly used e.g. in timing-laboratories when one
wants to measure many RF-sources (clock outputs like 1PPS or 10MHz) with
a single instrument (frequency or time-interval counter). The design is
for two independent MUX-boards to fit in a 1U 19” rack enclosure and may
fit in the OHWR “rackable 19” projects” category.
Two prototypes have been produced, with the second PCB-design
provisionally meeting the design goal for bandwidth/insertion-loss.
