Abstract
An RF front-end includes a receiver frequency band filter module, a low noise amplifier, a first power amplifier module, a second power amplifier module, and a transmit frequency band filter module. The receiver frequency band filter module filters a received RF signal and the low noise amplifier amplifies the signal in accordance with the first or the second RF front-end configuration signal. The first power amplifier module is enabled in accordance with the first RF front-end configuration signal to amplify the first outbound RF signal and the second power amplifier module is enabled in accordance with the second RF front-end configuration signal to amplify the second outbound RF signal. The transmitter frequency band filter module is enabled in accordance with the second RF front-end configuration signal to filter the second transmit RF signal.
