Abstract
A 44 GHz waveguide-based power amplifier module was developed using the double antipodal-finline transitions which also serve as a power combiner. The measured insertion loss of the proposed combiner was ~0.9 dB per transition around 44 GHz. The fabricated power amplifier module combining two 0.93 W monolithic microwave integrated circuit power amplifiers showed a saturated output power of 1.4 W with a high combining efficiency of 75% at 44 GHz
