W-band Dual Channel AM/PM Noise Measurement System - An Update

Abstract

We discuss the performance of a W-band "92-96" GHz amplitude modulated (AM) and phase modulated (PM) noise measurement system. The system uses two nearly identical channels to measure the residual noise in amplifiers in pulsed mode with a duty cycle of 10 % to 100 % (CW) at a given pulse repetition frequency (PRF). We describe details of the dual-channel measurement test set system and several design considerations that are essential for accurately extracting the device noise from measurement-system noise. We also discuss the modifications made to the synthesis scheme of the (92-96) GHz signal compared to the previous scheme. Finally, we present updated results for the source noise and the noise floor of the measurement system.
