Intermodulation product cancellation in communications

摘要

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 splitter. 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.
