AWMF-0157 28 GHz Silicon 5G Tx/Rx Quad Core IC
The AWMF-0157 is a highly integrated silicon quad core IC intended for 5G phased array applications. The device supports four Tx/Rx radiating elements, includes all requisite beam steering controls for phase and gain control, and operates in half duplex fashion to enable a single antenna to support both Tx and Rx operation. The device provides 25 dB gain and +14 dBm adjustable output power during transmit mode and 32 dB coherent gain, 5.5 dB NF, and -21 dBm IIP3 during receive mode. Additional features include gain compensation over temperature, temperature reporting, Tx power telemetry, and fast beam switching using on-chip beam weight storage registers. The device features ESD protection on all pins, operates from +1.8 V and 2.5V supplies, and is packaged in a 3.6 mm x 3.6 mm WLCSP (wafer level chip scale package) for easy flip chip 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
