POWER AMPLIFIER, TRANSCEIVER, AND BASE STATION

摘要

Embodiments of the present invention provide a power amplifier, a transceiver, and a base station. The power amplifier includes: a signal control unit, configured to generate a mode control signal and an auxiliary power amplifier control signal; a signal processing unit, configured to separately process an envelope signal and a radio-frequency signal; an envelope modulator, configured to output a fixed voltage or output an amplified envelope signal under the control of the mode control signal; a primary power amplifier, configured to perform amplification processing on the received radio-frequency signal that is input from the signal processing unit; and at least one auxiliary power amplifier, configured to operate or be disabled under the control of the auxiliary power amplifier control signal, and when in an operating state, perform amplification processing on the received radio-frequency signal that is input from the signal processing unit.

主权项

1. A power amplifier, comprising:
an envelope modulator, configured to output a fixed voltage under the control of an input mode control signal; a primary power amplifier, configured to receive the fixed voltage output by the envelope modulator, and to perform amplification processing on a received radio frequency signal by using the received fixed voltage as an operating voltage; and at least one auxiliary power amplifier, connected to the envelope modulator and connected with the primary power amplifier in parallel, configured to be in an operating state or a disabled state under control of an input control signal of auxiliary power amplifier, wherein when in the operating state, the at least one auxiliary power amplifier is configured to receive the fixed voltage output by the envelope modulator, and to perform amplification processing on the received radio frequency signal by using the received fixed voltage as an operating voltage.
