摘要:
A stage is provided for a receiver of a wireless device. The stage comprises a matching network that separates amplified signals of interest received from an amplifier from amplified unwanted signals received from the amplifier in conjunction with additional downstream filters. The stage also comprises a signal path that comprises components for receiving and processing the amplified signals of interest, and a shunt path that comprises 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.
