X-band silicon quad-core IC for radar and 5G phased array applications
The device supports four radiating elements, single-beam transmit and dual-beam receive, and includes all requisite beam-steering controls for 6-bit phase and gain control. It provides 21 dB gain during transmit mode, 21 dB gain in receive mode, +15 dBm output power during transmit, and 3.4 dB noise figure during receive. Additional features include gain compensation over temperature, temperature reporting, and fast beam-switching using eight on-chip beam weight storage registers.
The IC offers ESD protection on all pins, operates from +1.8 V, and is packaged in a 56-lead, 7- x 7-mm PQFN for easy installation in planar phased array antennas.
Key features of the AWS-0101 include: -16 dBm Rx IIP3; 6 bit phase control (LSB=5.625°); 6 bit gain control (LSB=0.5dB); 1.8 W DC Tx mode; and 1.8 W DC Rx mode.
