A CMOS monolithic transmit/receive switch comprises a single pole double throw switch (SPDT) module operable to selectively connect an antenna port to either a transmit port or to a receive port. A transmit matching network comprising a first transmission line matches the impedance of the transmit port of the SPDT module to a transmit impedance, and a first shunt transistor is operable to selectively ground a transmitter end of the first transmission line. A receive matching network comprising a second transmission line matches the impedance of the receive port of the SPDT module to a receive impedance, and a second shunt transistor is operable to selectively ground a receiver end of the second transmission line.
