Abstract
A reflector circuit is provided which responds to illuminating radiation with corresponding output radiation of increased magnitude relative to the illuminating radiation. The circuit comprises an antenna for receiving the illuminating radiation and emitting corresponding output radiation, a delay line providing a frequency selective limiting and signal storage characteristic and an amplifier assembly incorporating a reflection amplifier for providing signal amplification. The reflection amplifier is capable of providing high gains approaching +30 dB at relatively low current consumption, for example, tens of microamperes. The antenna provides an input signal upon receipt of the illuminating radiation, a portion of which is amplified, frequency selectively filtered, and then stored for a period after which it is emitted as the output radiation from the circuit. Switches may be incorporated and are operable to counteract spontaneous oscillation within the circuit.
