Abstract
A transmit/receive switching assembly includes a symmetrical PIN diode-based switch to selectively connect an antenna port to one of a transmit port and a receive port, transmit bias control circuitry that receives a first bias control signal, receive bias control circuitry that receives a second bias control signal, and shunt bias control circuitry coupled between the symmetrical PIN diode-based switch and a reference node. The first and second bias control signals are simultaneously and oppositely switchable between first and second voltage values and together configured to operate the switch between a transmit mode where RF signal flow is enabled from the transmit port to the antenna port and isolation is provided between the antenna port and the receive port, and a receive mode where RF signal flow is enabled from the antenna port to the receive port and isolation is provided between the antenna port and the transmit port.
