用于超外差接收机提供本振源的高功率510 GHz单片集成三倍频器
High power 510 GHz monolithic integrated frequency tripler for local oscillation sources in heterodyne receiver
摘要
Abstract
A high power 490～530 GHz monolithic integrated frequency tripler is demonstrated based on Gallium Arsenide material. Based on the proposed symmetrical and balanced configuration,the tripler could not only achieve good amplitude and phase balances for efficient power synthesis,but also provide a DC bias path without any bypass capacitor to ensure efficient frequency doubling efficiency. Tolerance simulations are also carried out to analyze the effects of key electrical and structural parameters of the diode on the frequency doubling perfor? mance in order to maximize the frequency doubling performance. Finally,the developed 510 GHz triplet,driven by approximately 80-200 mW input power,has an output power of 4-16 mW in the frequency range of 490～530 GHz,where the peak frequency doubling efficiency is 11％. At the 522 GHz frequency point,the triplex produc? es a maximum output power of 16 mW driven by an input power of 218 mW. The triplexer will later be used as the local oscillator source of a 1 THz solid-state external super outlier mixer.关键词
