Abstract

A multi-mode multi-band power amplifier (PA) module is described. In an exemplary design, the PA module includes multiple power amplifiers, multiple matching circuits, and a set of switches. Each power amplifier provides power amplification for its input signal when selected. Each matching circuit provides impedance matching and filtering for its power amplifier and provides a respective output signal. The switches configure the power amplifiers to support multiple modes, with each mode being for a particular radio technology. Each power amplifier supports at least two modes. The PA module may further include a driver amplifier and an additional matching circuit. The driver amplifier amplifies an input signal and provides an amplified signal to the power amplifiers. The additional matching circuit combines the outputs of other matching circuits and provides an output signal with higher output power. The driver amplifier and the power amplifiers can support multiple output power levels.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application asserts U.S. Provisional Serial No. 61 / 177,527, filed May 12, 2009, entitled "MULTI-MODE MULTI-BAND POWER AMPLIFIER AND ANTENNA FRONT END MODULE" Priority to the application, the provisional application assigned to the present assignee, is hereby expressly incorporated herein by reference. technical field [0003] The present invention relates generally to electronic devices, and more particularly to power amplifier (PA) modules for transmitters. Background technique [0004] In a wireless communication system, a transmitter may process (eg, encode and modulate) data to generate output samples. The transmitter may further condition (eg, convert to analog, filter, frequency upconvert, and amplify) the output samples to generate an output radio frequency (RF) signal. The transmitter can then transmit the output RF signal to the receiver via a wireless channel. A receiver may receive the transmit...
