The AD9375 is a highly integrated, wideband radio frequency (RF) transceiver offering dual-channel transmitters (Tx) and receivers (Rx), integrated synthesizers, a fully integrated digital predistortion (DPD) actuator and adaptation engine, and digital signal processing functions. The IC delivers a versatile combination of high performance and low power consumption required by 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 from 300 MHz to 6000 MHz, covering most of the licensed and unlicensed cellular bands.

It also supports observation receiver (ORx) and Tx synthesis bandwidths up to 250 MHz to accommodate digital correction algorithms.The transceiver consists of wideband direct conversion signal paths with state-of-the-art noise figure and linearity. Each complete Rx and Tx subsystem includes dc offset correction, quadrature error correction (QEC), and programmable digital filters, eliminating the need for these functions in the digital baseband. Several auxiliary functions such as an auxiliary analog-to-digital converter (ADC), auxiliary digital-to-analog converters (DACs), and general-purpose input/outputs (GPIOs) are integrated to provide additional monitoring and control capability.An ORx channel with two inputs is included to monitor each Tx output and implement calibration applications.
