Abstract
RF filtering circuitry includes a first input/output node, a second input/output node, a common node, first filtering circuitry, second filtering circuitry, and transmit signal cancellation circuitry. The first filtering circuitry is coupled between the first input/output node and the common node, and is configured to pass RF transmit signals within one or more transmit signal frequency bands while attenuating signals outside the one or more transmit signal frequency bands. The second filtering circuitry is coupled between the second input/output node and the common node, and is configured to pass RF receive signals within one or more receive signal frequency bands while attenuating signals outside the one or more receive signal frequency bands. The transmit signal cancellation circuitry is coupled between the common node and the second input/output node and is configured to generate a transmit cancellation signal from the RF transmit signals.
