Abstract :
This paper describes the analysis and design of a microstrip-to-waveguide transition/combiner that is eminently suitable for millimeter wave power amplifier application. Analytical and experimental work at Ka band on a two-way combiner showed an insertion loss of 0.5 dB. The port VSWR´s were less than 1.6:1 and the input-to-input port isolation was greater than 16 dB over a 3 GHz band. This novel design is highly manufacturable and compatible with integration of monolithic amplifiers and other circuits.<>
