Intermodulation products in the amplifier circuitry of a communications
device are cancelled. A primary carrier is processed in a first main
branch of amplifier circuit. The primary carrier is coupled to a
secondary branch through a first signal splitters. Intermodulation
products are created from a portion of the primary carrier coupled
through the secondary branch. The intermodulation products are then
coupled back into the main branch to produce an output signal provided to
a transmitter.
