  • TX CANCELLATION SYSTEM BY SOURCE INJECTION
    Publication number: 20180123634
    Abstract: Cancellation of a leaked transmission signal received together with a received signal is cancelled at a receiver amplifier in a system made up of the receiver amplifier, a power amplifier, and a duplexer that couples both to an antenna. A portion of the amplified transmission signal from the power amplifier is split off prior to the duplexer. That portion is controllably applied to the receiver amplifier. A feedback loop monitors the amplified output of the receiver amplifier and varies the gain and phase of the portion of the amplified transmission signal in order to minimize the amount of transmission signal in the amplified output of the receiver amplifier.
