A Highly Miniaturized Active 90° Power Combiner MMIC Employing CE and CC Circuits

In this work, a highly miniaturized active 90° power combiner, employing InGaP/GaAs heterojuntion bipolar transistors (HBT), was fabricated on a GaAs substrate for MMIC applications. A novel composite structure employing common-emitter (CE) and common-...
A 90° power combiner has been used for signal mixing at the intermediate frequency (IF) output port of an image rejection mixer. 1,2 Until now, a passive branch-line coupler was mainly employed for 90° power combining. 1,3 However, the passive branch-line coupler occupies a very large circuit area. For...
