MODULATING REFLECTOR CIRCUIT

摘要

A modulating reflector circuit arrangement comprising a transistor (1) configured by means of a feedback arrangement (10) upon operation within a linear region of the transistor's current/voltage characteristic to reflect an incoming amplitude modulated signal with an increased amplitude and modulating means (14) operable to modulate power to the transistor (1) with a periodic waveform in which the reciprocal of the period of the periodic waveform is the required sideband frequency of the reflected signal and the waveform is selected such that the arrangement reflects a substantially single sideband signal.
