The ADAR1000 from Analog Devices is a 4-Channel X and Ku Band Beamforming IC that operates from 8 to 16 GHz. It provides a gain adjustment range of more than 31 dB and a full 360° phase adjustment range in the radio frequency (RF) path, with 6-bit resolution (less than ≤0.5 dB and 2.8°, respectively).
The IC supports half-duplex for both receive and transmit modes. In receive mode, input signals pass through four receive channels and are combined in a common RF_IO pin. In transmit mode, the RF_IO input signal is split and passes through the four transmit channels.
The ADAR1000 has an integrated temperature sensor and four -20 to 10 dBm power detectors which can be controlled via an 8-bit ADC. It has a single-pin transmit/receive control & programmable bias modes for external transmit/receive modules and also has dedicated transmit/receive load pins that provide synchronization of all core chips in the same array.
The IC beamforming IC requires a DC supply of -5.5 to +3.6 V and can be controlled via a 4-wire SPI interface. It is available in an LGA package that measures 7 x 7 mm and is ideal for phased array radars and satellite communication systems.
