Abstract:
A radio frequency communications system with a first operating frequency band and a second operating frequency band is disclosed. There is a first antenna. A transceiver has a first transmission port, a second transmission port, a first reception port, and a second reception port. In a first front end circuit, a first port is coupled to the antenna, and a second port is coupled to the transceiver. The first front end circuit has a first low noise amplifier, a second low noise amplifier, a first power amplifier, and a second power amplifier. A switching circuit connects the first transmission port, the first reception port, the second transmission port, and the second reception port to the second port of the first front end circuit. The antenna is distant from the transceiver, while the first front end circuit is proximal to the antenna. The first switching circuit is proximal to the transceiver.
