AWS-0104 X-Band Silicon Radar Quad Core IC
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 21 dB gain during transmit mode, 21dB gain in receive mode, +15 dBm output power during transmit, and 3.4 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.
*NOTE: Coherent gain (CG) is the RF gain with all Rx input ports energized and is most useful for assessing RF power handling in the beam forming network. Electronic gain (EG) is the RF gain exclusive of the 4:1 sum and is most useful for cascaded NF and gain calculation. The total gain of the antenna aperture can be calculated from EG + 10*log(n), where n is the number of antenna elements in the array. Single path gain (SPG) is the RF gain with only one input port energized. This is representative of the RF gain measured in a 2 port measurement system, such as with the Developer’s Kit.
CG = SPG + 12 dB = EG + 6 dB for a quad IC
