This RF IC is highly integrated and contains 16 independent transmit and receive channels. In transmit mode, the RFC input signal is split using 1:16 power splitters and passes through the 16 independent transmit channels. In receive mode, input signals pass through the 16 independent channels and are bined with 16:1 biners to the RFC pin. In transmit mode, each channel includes a vector modulator (VM) to control phase and two digital variable gain amplifiers (DVGAs) to control amplitude. In receive mode, each channel includes a VM to control phase and a DVGA to control amplitude. The VM provides a full 360° phase adjustment range in either transmit or receive mode, providing 6 bits of resolution for 5.625° phase steps. The total DVGA dynamic range adjustment range in transmit mode is 34 d B, providing 6 bits of resolution, resulting in 0.5 d B amplitude steps, and 5 bits of resolution, resulting in 1 d B amplitude steps. In receive model the total dynamic range is 17 d B providing, 6 bits of resolution, resulting in 0.5 d B amplitude steps. The DVGAs provide a flat phase...
