Beam hopping self addressed packet switched communication system with power gating

摘要

A downlink beam frame signal processing system ( 100 ) for a communication satellite includes a packet switch ( 608 ) that routes self addressed uplink data to a memory ( 804 ). The memory ( 804 ) stores queues for at least a first and a second downlink beam hop locations ( 302, 304 ). The processing system ( 100 ) also includes a power amplifier ( 108 ) that amplifies a waveform formed using the uplink data. A power gating circuit ( 1200 ) coupled to the power amplifier ( 108 ) includes a power gate input ( 1216 ) responsive to a power gating signal to remove RF power from at least a portion of the waveform before transmission.
