Abstract
A burst signal generating apparatus and related method includes a modulator circuit for modulating a carrier wave of an intermediate frequency signal with a modulating signal. The output of the modulator having a carrier wave frequency is converted to a radio frequency which is amplitude controlled in response to a burst control signal. The carrier wave of the intermediate frequency is switched in response to a burst control signal. Thus, a carrier wave of the radio frequency signal has a desired envelope, permitting ready suppression of the carrier wave during pauses between burst signals.
