Abstract

A wireless device with power combining power amplifiers to support transmission on multiple antennas is disclosed. The power amplifiers may be operated together to obtain higher output power or separately to support transmission on multiple antennas. In an exemplary design an apparatus includes first and second power amplifiers. The first power amplifier amplifies a first input signal and provides a first output signal for a first antenna in a first operating mode (e.g. a MIMO mode or a transmit diversity mode). The second power amplifier amplifies the first input signal or a second input signal and provides a second output signal for a second antenna in the first operating mode. The first and second power amplifiers are power combined in a second operating mode to provide a third output signal which has a higher maximum output power than the first or second output signal.
