Abstract
A front end circuit for coupling an antenna to a first radio frequency (RF) transceiver and a second RF transceiver is contemplated. The RF transceivers have a signal input, a signal output, a receive enable line and a transmit enable line. In addition to an antenna port, the front end circuit has a first power amplifier and a first low noise amplifier both coupled to first RF transceiver, and a second power amplifier and a second low noise amplifier both coupled to the second RF transceiver. The front end circuit includes a matching network that couples the power amplifiers and the low noise amplifiers, the various outputs and inputs thereof being common.
