Millimeter-wave hybrid coupled reflection amplifiers and multiplexers
Abstract
Multiple stage hybrid coupled reflection amplifiers and frequency multipliers are modeled using two-port analysis. A two-stage (4 diode) microstrip InP Gunn amplifier and a four-section suspended substrate multiplexer were fabricated in K-alpha band. Analysis shows that the performance of the hybrid coupled amplifier, both for packaged diodes and pure negative resistance (ideal monolithic) devices, is extremely sensitive to input and output VSWR's.
