A 200 MHZ - 2250 MHZ/400 MHZ - 4500 MHZ REGENERATIVE FREQUENCY DOUBLER IN A 0.35um SiGe PROCESS

摘要

A wideband frequency doublet used in a satellite modulator for DVB-RCS (DVB Return Channel via Satellite) applications is presented. The doubler is based on a regeneration configuration and fabricated in a 0.35um SiGe process. The doubler exhibits large output signal swing and very low phase noise degradation with an output bandwidth of 4.1GHz.
