摘要：
This paper presents the design and performance of a broadband millimeter-wave frequency doubler MMIC using active 0.15μm GaAs PHEMT and operating at output frequencies from 20 to 44 GHz.This chip is composed of a single ended-into differential-out active Balun,balanced FETs in push-push configuration,and a distributed amplifier. The MMIC doubler exhibits more than 4 dB conversion gain with 12 dBm of output power,and the fundamental frequency suppression is typically -20 dBc up to 44 GHz.The MMIC works at V;=3.5 V,V;=-3.5 V,I;=200 mA and the chip size is 1.5×1.8 mm;.
