Overview
The AD9375BBCZ-REEL is a highly integrated, wideband radio frequency (RF) transceiver produced by Analog Devices Inc. This single-chip transceiver IC offers dual-channel transmitters (Tx) and receivers (Rx), along with integrated synthesizers, a fully integrated digital predistortion (DPD) actuator and adaptation engine, and digital signal processing functions. It is designed to meet the high performance and low power consumption requirements of 3G/4G small cell and massive multiple input, multiple output (MIMO) equipment in both frequency division duplex (FDD) and time division duplex (TDD) applications. The AD9375 operates across a wide frequency range from 300 MHz to 6000 MHz, covering most licensed and unlicensed cellular bands.
