Beamforming in radio frequency (RF) communication systems using frequency division duplexing (FDD) is disclosed. In one aspect, a front end system includes a power amplifier, a transmit filter electrically connected to an output of the power amplifier and passing an uplink frequency range of a frequency band, a receive filter passing a downlink frequency range of the frequency band, a low noise amplifier (LNA), and a switch having a first state in which the switch electrically connects an input of the LNA to the receive filter and a second state in which the switch electrically connects the output of the power amplifier to the receive filter. The front end system is operable in an FDD mode in which the front end system simultaneously sends a transmit beam on the uplink frequency range of the frequency band and receives a receive beam on a downlink frequency range of the frequency band.
