1. A broadband switch comprising:
a first electromagnetically isolated cavity;
a second electromagnetically isolated cavity;
a power input disposed in the first electromagnetically isolated cavity;
a plurality of signal inputs disposed in the second electromagnetically isolated cavity; and
a plurality of analog passive relays, each associated with one or more signal inputs,
wherein:
the plurality of relays are organized as two stages of ganged staged relays and a final output stage;
power interface lines associated with the power input are disposed orthogonal to data input lines associated with the plurality of signal inputs to provide at least 100 dB of electrical isolation;
the broadband switch lacks a common ground plane to prevent ground loops; and
the broadband switch lacks shared return lines to reduce mutual inductance.
