Abstract
Beamforming in radio frequency (RF) communication systems using frequency division duplexing (FDD) are provided. In certain embodiments, a front end system includes a first transmit path configured to process a first radio frequency transmit signal of a frequency band, the transmit path including a power amplifier and a transmit filter having a passband that passes an uplink frequency range of the frequency band, and a receive path configured to process a first radio frequency receive signal of the frequency band. The receive path includes a low noise amplifier, a switch, and a receive filter having a passband that passes a downlink frequency range of the frequency band, and the switch has a first state in which an input of the low noise amplifier is coupled to the receive filter and a second state in which an output of the power amplifier is coupled to the receive filter.
