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. 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 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. This channel also connects to three sniffer receiver (SnRx) inputs that can monitor radio activity in different bands.

The high speed JESD204B interface supports lane rates up to 6144 Mbps. Four lanes are dedicated to the transmitters and four lanes are dedicated to the receiver and observation receiver channels.

The fully integrated phase-locked loops (PLLs) provide high performance, low power, fractional-N frequency synthesis for the Tx, the Rx, the ORx, and the clock sections. Careful design and layout techniques provide the isolation demanded in high performance base station applications. All voltage controlled oscillator (VCO) and loop filter components are integrated to minimize the external component count.

The device contains a fully integrated, low power DPD actuator and adaptation engine for use in PA linearization. The DPD feature enables use of high efficiency PAs, significantly reducing the power consumption of small cell base station radios while also reducing the number of JESD204B lanes necessary to interface with baseband processors.

A 1.3 V supply is required to power the AD9375 core, and a standard 4-wire serial port controls it. Other voltage supplies provide proper digital interface levels and optimize transmitter and auxiliary converter performance. The AD9375 is packaged in a 12 mm × 12 mm, 196-ball chip scale ball grid array (CSP_BGA).

Product Detail

The ADRV-DPD1/PCBZ is a 24 dBm per path, 2 × 2 multiple input, multiple output (MIMO) radio board, which uses the AD9375, a highly integrated radio frequency (RF) transceiver with integrated digital predistortion (DPD). The radio board is designed to be used with the dual connector interposer board to interface with the EVAL-TPG-ZYNQ3 or other Xilinx® or Avnet evaluation boards for the Xilinx Zynq-7000 field programmable gate array (FPGA) platform, which has a dual core ARM Cortex®-A9 processor running a Linux® variant.

The AD9375 small cell evaluation software (SCES), AD9375 Small Cell Radio Reference Design Evaluation Software GUI, can configure and control the ADRV-DPD1/PCBZ board. Note that the Mykonos transceiver evaluation software (MTES) and DPD graphical user interface (GUI) software are not compatible with the ADRV-DPD1/PCBZ.

Full specifications on the AD9375 are available in the AD9375 data sheet available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the evaluation board.
