Abstract
Systems and methods may be provided for a CMOS RF antenna switch. The systems and methods for the CMOS RF antenna switch may include an antenna that is operative to transmit and receive signals over at least one radio frequency (RF) band, and a transmit switch coupled to the antenna, where the transmit switch is enabled to transmit a respective first signal to the antenna and disabled to prevent transmission of the first signal to the antenna. the systems and methods for the CMOS RF antenna switch may further include a receiver switch coupled to the antenna, where the receiver switch forms a filter when enabled and a resonant circuit when disabled, where the filter provides for reception of a second signal received by the antenna, and where the resonant circuit blocks reception of at least the first signal.
