摘要

A series of 31.3-45.0GHz millimeter-wave components including 31.3-45GHz low-noise amplifiers, band-pass and highpassfilters, a cascode PHEMT mixer, and 4-12GHz IF amplifiers are developed in Taiwan. The local oscillator for band-1 is also developed, including the phase-locked GaAs HBT MMIC voltage-controlled oscillator cascaded by a bufferamplifier and a baseline design based on a YIG-tunes oscillator with active frequency doubler. The measured RMS jitterof the HBT VCO LO is around 51 fs and the version of YIG is less than 40fs over 1K to 1MHz frequency offset.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
