ABSTRACT:
The present invention provides a wideband power amplifier for a multi-mode or multi-band wireless communication device. The wideband power amplifier is configured to amplify signals in different frequency bands corresponding to different operating modes. In general, the wideband power amplifier includes multiple matching circuits that operate to combine the signals in the different frequency bands and provide a combined signal to each transistor in an output stage of the wideband power amplifier.
