Abstract: A radio frequency receiver includes a receiver circuit for processing RF signals, an antenna to receive millimeter wave RF signals, and an attenuator circuit, coupled between the receiver circuit and antenna. In one embodiment, the attenuator circuit may be used to determine a signal strength of the millimeter wave RF signals, compare this signal strength to a first threshold value. If the signal strength is above the first threshold value, a level of attenuation applied to the millimeter wave RF signals may then be increased.

Abstract: An energy-dispersal signal rejection circuit adapted for use in a direct-broadcast-from-satellite system rejects an energy-dispersal signal from an input signal which includes a video signal composed with the energy-dispersal signal by generating a cancellation signal synchronized with, and having a phase and amplitude determined in accordance with the energy-dispersal signal, and such cancellation signal is composed with the input signal, for example by adding the two signals, so that the energy-dispersal signal is cancelled from the input signal and the video signal is produced as an output signal.

Abstract: An apparatus for receiving broadcast FM waves using an FM (Frequency Modulated) detector is disclosed in which an output signal level of an automatic gain controller (AGC) (17) is controllable so that when the C/N ratio is reduced and the output level of the automatic gain controller is reduced, the loop gain of a PLL type FM demodulator is accordingly reduced and response is delayed with the bandwidth being narrowed. Therefore, since delayed threshold extension is applied thereby, no signal noise, such as white points appearing on an image screen, will occur.
