Abstract
We present improved performance for a 92 to 96 GHz cross-spectrum phase modulated (PM) noise measurement system reported. The system is principally designed to measure amplifiers in pulsed mode as well as in CW mode at a given pulse repetition frequency. This paper reports only the CW mode of operation. Data for the noise-floor of the measurement system as well as PM noise of several W- band active components are presented. This work also discusses an improved performance frequency synthesizer that operates in the 92 to 96 GHz range.
