Beamformers, Phase Shifters, and Vector Modulators

Analog Devices beamformers offer best-in-class performance with the highest levels of integration for optimum scalability and antenna array simplification. These beamformers integrate multiple channels, and each has independent phase and amplitude control in their transmit and receive paths, allowing the RF and microwave front end to electronically steer the antenna beams for an optimum transmission aiming pattern. The high level of integration enables systems, whether they are for communications, radar, electronic warfare or radio, to deliver higher levels of performance in a smaller size while reducing system costs. The beamformer IC integrates additional functionality such as digital control circuitry, power detectors, on-chip memory, power management blocks, and more for a complete antenna steering solution.

Analog Devices digital phase shifters change the phase of RF, microwave, or millimeter wave signals while providing no amplitude change. They are used in a variety of applications, including RF PA linearization/RF distortion, amplitude and phase modulation, variable attenuators, and fiber optics.

Analog Devices high dynamic range vector modulator RF ICs offer 360° continuous phase control, a continuous gain control of 40 dB, and a low output noise floor of at least –160 dBm/Hz at the maximum gain setting. Applications: • Cellular and WiMAX systems • Wireless infrastructure • Predistortion or feedforward linearization • Beamforming and nulling circuits
