Abstract
A microwave power combining FET amplifier includes T-type input and output branch circuits 13, 14 for power splitting and combining, and interstage matching circuits 6a, 6b laterally connected at their mid-points a, b by a resistance circuit 15 which absorbs odd propagation mode waves reflected back from the output combiner due to non-uniformities between the post-stage FETs 4a, 4b.
