Patent ID: 6957078

Claim:
A power gating module for power gating a downlink transmitter that is configured to transmit a downlink beam frame signal, the power gating module comprising: a power amplifier for amplifying transmission frame signal, including at least a first header signal, a first payload signal a second header signal and a second payload signal; and a power gating circuit coupled to the power amplifier the power gating circuit including a power gate input and responsive to a power gating signal to remove power from the downlink transmitter during transmission of at least one of the first header signal and first payload signal in combination and the second header signal and second payload signal in combination before amplification by the power amplifier; wherein the power gating circuit comprises a digital modulator with a gating control input connected to the power gate input and a bandpass filter with a predetermined passband coupled to a modulator output of the digital modulator.
