Abstract
In this paper experimental data on the FM and AM noise of low-noise microwave tubes, "solid-state klystrons," and solid-state chains of the types used in Doppler radars are presented. The tube types include magnetrons, klystrons, and triodes. Data on solid-state chains of the type consisting of a VHF crystal-controlled transistor oscillator, followed by a VHF transistor power amplifier, and a varactor frequency multiplier are also presented. The spectral shape of the solid-state chain is shown to differ from those of the microwave tubes and that of the "solid-state klystron." Comparisons are made between the various devices.Keywords
