摘要
Abstract
Two different frequency bandwidth subharmonic mixers (SHM) using planar Schottky mixing diodes are discussed and fabricated.Full-wave analysis is carried out to find the optimum diode embedding impedances with a lumped port for modeling the nonlinear junction.The SHM circuit is divided into several different parts and each part is optimized using the calculated diode impedances.The divided parts are then combined and optimized together.The exported S-parameter files of the global circuit are used for conversion loss (CL) discussion.For the 150 GHz SHM,the lowest measured CL is 10.7 dB at 153 GHz,and typical CL is 12.5 dB in the frequency range of 135-165 GHz.The lowest measured CL of the 180 GHz SHM is 5.8 dB at 240 GHz,and typical CL is 13.5 dB and 11.5 dB in the frequency range of 165-200 GHz and 210-240 GHz,respectively.关键词
