摘要： A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.

摘要： A communications subsystem for a wireless device for correcting errors in a reference frequency signal. The communications subsystem comprises a frequency generator for generating the reference frequency signal and a closed loop reference frequency correction module that generates a reference frequency adjustment signal for correcting the reference frequency signal when the communications subsystem operates in closed loop mode. The subsystem further includes an open loop frequency correction means that that samples values of the reference frequency adjustment signal during the closed loop mode and generates a frequency correction signal for correcting the reference frequency signal when the communications subsystem operates in a mode other than closed loop mode.

摘要： A pre-processing stage is provided for a receiver of a wireless device. The pre-processing stage includes an amplifier that receives signals of interest and unwanted signals and produces amplified signals of interest and amplified unwanted signals, and a matching network that separates the amplified signals of interest from the amplified unwanted signals in conjunction with additional downstream filters. The preprocessing stage also includes a signal path that includes components for receiving and pre-processing the amplified signals of interest, and a shunt path that includes components for adjusting reflected energy sent back to the amplifier for limiting the output swing of the amplifier in a frequency band corresponding to the amplified unwanted signals.
