ABSTRACT:
The invention is a low loss multiple pole multiple throw microwave switch having a transmission line for each of a plurality of outputs. A phase shifting device is provided in each transmission line operable between first and second states to shift the phase of a microwave signal transmitted therethrough. A matrix of signal dividers and cross-over networks cooperate with the phase shifting devices to produce additive and substractive vertical signal components such that all of the components at one output are additive and the signal components at all the other outputs have a vector sum of zero.
