Abstract
Near carrier amplitude and phase noise modulations have been measured for low noise (receiving type) and medium power (20 w) TWT amplifiers at 6 GHz. The measured noise is greater than predicted by the noise figure measured 30 MHz from the carrier. Below 20 kHz, at least part of the excess can be accounted for by phase modulation products coherent with the power line frequency.
