An amplifier system includes an input network having a plurality of input ports; an output network having a plurality of output ports; a plurality of amplification units coupled between the input network and the output network, the plurality of amplification units configured to amplify signals from the plurality of input ports; and a calibration unit coupled between the plurality of amplification units and the output network to calibrate amplified signals from the plurality of amplification units.

Method and apparatus for calibration and equalization of multiport amplifiers (MPAs)

An arrangement is disclosed for providing the functionality of a four port, four channel rotary switch. The arrangement includes a first four port rotary microwave switch, the first switch including a first rotor and a first set of four waveguide ports, and a second four port rotary microwave switch, communicatively coupled to the first switch, the second switch including a second rotor and a second set of four waveguide ports. Each of the first switch and the second switch has at most three channels.
