Abstract
A radio frequency (RF) transmit-receive switch has an antenna port, first and second transmit differential ports and first and second receive differential ports. Transmit transistor switches are connected to the transmit differential ports. Primary and secondary windings of a transmit coupled inductor transformer are connected to the transmit transistor switches. Receive transistor switches are connected to the receive differential ports. Primary and secondary windings of a receive coupled inductor transformer are connected to the receive transistor switches. A first balun inductive winding is connected to the antenna port, and a second balun inductive winding is connected to the transistor switches.
