A universal power amplifier for amplifying and filtering transmit and receive signals has an input switch for switching transmit and receive signals. Transmit paths in the universal power amplifier are connected to the input switch. The transmit paths comprise filters for filtering the transmit signals and amplifiers for amplifying the transmit signals. Receive paths are connected to the input switch. The receive paths filter and amplify the receive signals. A first receive path shares one of the filters a first transmit path to filter a receive signal. A power output stage is connected to the transmit paths for amplifying the transmit signals into high-power transmit signals. A transmit/receive switch is connected to the power output stage and the receive paths for switching the high-power transmit signals and receive signals to an antenna.
