METHOD AND APPARATUS FOR GENERATING PHASE SHIFT CONTROL SIGNALS

A phase shifter controller arranged to generate phase shift control signals for at least one phase shifter. The phase shifter controller is arranged to receive a first phase value θ1, receive a second phase value θ2, and output phase shift control signals. The phase shifter controller comprises a digital synthesizer arranged to compute a first digital phase shift control value based on the received first phase value θ1, and compute a second digital phase shift control value based on the received second phase value θ2. The phase shifter controller further comprises digital to analogue converters arranged to generate the phase shift control signals based on the derived first and second digital phase shift control values.
