Miniaturized Low Cost 30 GHz Monolithic Balanced BPSK and Vector Modulators: Part II

The physical realiztion of a newly designed compact microstrip coupler and the design and performance of a MMIC BPSK and vector modulator that utilizes the coupler
Miniaturized Low Cost 30 GHz Monolithic Balanced BPSK and Vector Modulators: Part II Part one of this two-article series analyzed single-stage and balanced topologies in detail. It was illustrated that a common technique for realizing direct biphase-shift keying (BPSK) microwave modulators is to employ reflection-type topology with cold pseudomorphic...
