AD9375 Integrated, Dual, Pre-Distortion 3G/4G Transceiver

ADI’s AD9375 is a highly integrated, wideband radio frequency (RF) transceiver offering dual-channel transmitters (Tx) and receivers (Rx), integrated synthesizers, a fully integrated digital pre-distortion (DPD) actuator and adaptation engine, and digital signal processing functions. This transceiver 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. The DPD algorithm supports linearization on signal bandwidths up to 40 MHz depending on the power amplifier (PA) characteristics (for example, two adjacent 20 MHz carriers). The IC supports Rx bandwidths up to 100 MHz. It also supports observation receiver (ORx) and Tx synthesis bandwidths up to 250 MHz to accommodate digital correction algorithms. The device comes in a 196-pin LFBGA package that has an operating temperature range of -40°C to +85°C. A development platform (ADRV-DPD1/PCBZ) is available for faster design, prototyping, and testing for faster time to market. The AD9375 is ideal for 3G/4G base stations and MIMO antenna systems.
