ABSTRACT:
A high power solid state load comprises at least two arrays of solid state switching devices. The switching devices can comprise PIN diodes formed on a semi-conductor wafer. The arrays are connected to two ports of a combiner network and each of the switching devices in the arrays is driven either fully on or fully off in order to provide a load having high power handling capabilities and a large number of discrete impedance states.
