The AWS-0104 is a highly integrated silicon quad core IC intended for radar and 5G phased array applications. The device supports four radiating elements, single beam transmit, and single beam receive and includes all requisite beam steering controls for 6 bit phase and gain control. The device provides 20 dB gain during transmit mode, 20 dB gain in receive mode, +13 dBm output power during transmit, and 4.0 dB NF during receive. Additional features include gain compensation over temperature, temperature reporting, and fast beam switching using eight on-chip beam weight storage registers. The device features ESD protection on all pins, operates from a +1.8V supply, and is packaged in a 56 lead 7x7 QFN for easy installation in planar phased array antennas.
