Abstract: An asymmetric power amplifier includes: an input port for receiving a multi carrier signal including a first subcarrier and a second subcarrier; a first tunable analog filter for filtering the received multi carrier signal into a first signal of the first subcarrier; a second tunable analog filter for filtering the received multi carrier signal into a second signal of the second subcarrier; an amplifier for amplifying the first signal of the first subcarrier; a power amplifier for power amplifying the second signal of the second subcarrier; a combiner for power combining the amplified first signal and the amplified second signal to form a power combined multi carrier signal; and an output port for outputting the power combined multi carrier signal to be transmitted by a transmitter.
