Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for signal processing, comprising: a first power amplifier receiving a first input signal and providing power amplification for the first input signal when the first power amplifier is selected; a first matching circuit coupled to the first power amplifier and providing a first output signal; a second power amplifier receiving a second input signal and providing power amplification for the second input signal when the second power amplifier…
