Paper Abstract

A series of 31.3-45.0GHz millimeter-wave components including 31.3-45GHz low-noise amplifiers, band-pass and highpass filters, 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 buffer amplifier and a baseline design based on a YIG-tunes oscillator with active frequency doubler. The measured RMS jitter of the HBT VCO LO is around 51 fs and the version of YIG is less than 40fs over 1K to 1MHz frequency offset.
