<p>Systems and methods are provided for modulating a radio frequency, RF, carrier signal with a baseband input signal and amplifying the modulated RF carrier signal to provide an amplified RF signal. A quadrature combiner (30) is configured to provide the amplified RF signal at an associated output port (19). A main amplifier (22, 23) is configured to receive a first modulated RF signal (16, 17) and provide a main output (26, 27) to one of a through port (THRU) and a coupled port (CPL) of the quadrature combiner (30). An auxiliary amplifier (24) is configured to receive a second modulated RF signal (18) and provide an auxiliary output (28) to an isolation port (ISO) of the quadrature combiner (30).</p> |
