Abstract
The noise, locking bandwidth and gain characteristics of the injection-locked IMPATT amplifier are discussed and related to the requirement for f.d.m. telephone transmission over microwave circuits. It is shown that the unloaded noise produced by the IMPATT diode limits its application to low-gain operation in medium-capacity radio links, although the gain obtainable can be improved by employing multistage amplifiers.
