Beamformer is an indispensible part of any phased array system. Analog beamformer is the simpler method where the individual signals received from array of antennas are co-phased and summed to maximize the signal reception. The co-phasing is achieved through data independent weights which are predefined as per direction of arrival. These weights are applied to the analog phase shifter IC, which produces a set of phases in order to compensate the directional phase shifts. Signals are then combined with a power combiner. For realistic demonstration, signals from different locations are transmitted through a transmitter with a horn antenna. The beamformer successfully enhances the signal from the direction of interest.
