GENERAL DESCRIPTION
the Tx, the Rx, the ORx, and the clock sections. Careful design The AD9375 is a highly integrated, wideband radio frequency (RF) and layout techniques provide the isolation demanded in high transceiver offering dual-channel transmitters (Tx) and receivers performance base station applications. Al voltage controlled (Rx), integrated synthesizers, a ful y integrated digital predistortion oscil ator (VCO) and loop filter components are integrated to (DPD) actuator and adaptation engine, and digital signal processing minimize the external component count. functions. The IC delivers a versatile combination of high The device contains a fully integrated, low power DPD actuator performance and low power consumption required by 3G/4G and adaptation engine for use in PA linearization. The DPD feature small cell and massive multiple input, multiple output (MIMO) enables use of high efficiency PAs, significantly reducing the power equipment in both frequency division duplex (FDD) and time consumption of small cell base station radios while also reducing division duplex (TDD) applications. The AD9375 operates from the number of JESD204B lanes necessary to interface with baseband 300 MHz to 6000 MHz, covering most of the licensed and unlicensed processors. cel ular bands. The DPD algorithm supports linearization on A 1.3 V supply is required to power the AD9375 core, and a signal bandwidths up to 40 MHz depending on the power amplifier standard 4-wire serial port controls it. Other voltage supplies (PA) characteristics (for example, two adjacent 20 MHz carriers). provide proper digital interface levels and optimize transmitter The IC supports Rx bandwidths up to 100 MHz. It also supports and auxiliary converter performance. The AD9375 is packaged in a observation receiver (ORx) and Tx synthesis bandwidths up to 12 mm × 12 mm, 196-ball chip scale ball grid array (CSP_BGA). 250 MHz to accommodate digital correction algorithms.
