Abstract :
A Ka-band GaN MMIC power amplifier (PA) with a novel 4-way combiner/divider is presented. The on-chip balanced 4-way combiner results in improved input and output return loss, and increased bandwidth. The 32 – 38 GHz two-stage PA produces a maximum power of 6 watts under class-A operation. This is the first report of this novel compact, combiner concept.
