26.5 GHz–29.5 GHz 4-Channel Dual-Polarized Analog Beamforming Integrated Circuit

The MMW9012K is a highly integrated 5G 4-channel dual-polarized analog beamforming IC digitally controlled either via a high-speed SPI bus or via an LVDS link. The MMW9012K has 8-bits phase and gain resolution. Each channel consists of a transmit chain (TX) and a receive chain (RX). Both TX and RX chains have a buffer, a phase shifter and a variable gain amplifier (VGA). On-chip power detectors allow measuring the power levels on all antenna ports in TX mode. The digital interface controls all MMW9012K functional registers. The MMW9012K comes in a very small FO-WLPBGA package of 6.5 mm x 6.1 mm x 0.56 mm with 182 bumps.
