Abstract
A front end circuit for selectively coupling a first antenna and a second antenna to a transmit chain and a receive chain of a radio frequency (RF) transceiver is disclosed. There is a first power amplifier having an input connectible to the transmit chain of the RF transceiver, a first low noise amplifier having an output connectible to the receive chain of the RF transceiver, and a second low noise amplifier with an input connectible to the second antenna, as well as an output connectible to the receive chain of the RF transceiver. A first matching and switch network is connected to the first antenna, the output of the first power amplifier, and the input of the first low noise amplifier. Transmit signals from the first power amplifier and receive signals from the first antenna are selectively passed to the first antenna and the first low noise amplifier.
