摘要
In this paper, a miniaturized 18-40 GHz sub-harmonic mixer is designed and implemented with 0.15 mu m GaAs pHEMT process. The proposed mixer employs anti-parallel diode pair with parallel to ground configuration, and a novel coupler structure to feed RF and LO signals, resulting in broadband performance and compact chip size. The measured conversion loss is 10.3-13.5 dB in a wide operation frequency band of 18-40 GHz. The chip size is 0.66 mm(2).
