The AD9361 is a high performance, highly integrated radiofrequency (RF) Agile Transceiver™ designed for use in 3G and4G base station applications. Its programmability and widebandcapability make it ideal for a broad range of transceiver applications.The device combines a RF front end with a flexible mixed-signalbaseband section and integrated frequency synthesizers, simplifyingdesign-in by providing a configurable digital interface to aprocessor. The AD9361 receiver LO operates from 70 MHz to6.0 GHz and the transmitter LO operates from 47 MHz to 6.0 GHzrange, covering most licensed and unlicensed bands. Channelbandwidths from less than 200 kHz to 56 MHz are supported.The two independent direct conversion receivers have state-of-the-artnoise figure and linearity. Each receive (RX) subsystem includesindependent automatic gain control (AGC), dc offset correction,quadrature correction, and digital filtering, thereby eliminatingthe need for these functions in the digital baseband. The AD9361also has flexible manual gain modes that can be externallycontrolled. Two high dynamic range analog-to-digital converters(ADCs) per channel digitize the received I and Q signals and passthem through configurable decimation filters and 128-tap finiteimpulse response (FIR) filters to produce a 12-bit output signal atthe appropriate sample rate.The transmitters use a direct conversion architecture that achieveshigh modulation accuracy with ultralow noise. This transmitterdesign produces a best in class TX error vector magnitude (EVM)of <−40 dB, allowing significant system margin for the externalpower amplifier (PA) selection. The on-board transmit (TX)power monitor can be used as a power detector, enabling highlyaccurate TX power measurements.The fully integrated phase-locked loops (PLLs) provide lowpower fractional-N frequency synthesis for all receive andtransmit channels. Channel isolation, demanded by frequencydivision duplex (FDD) systems, is integrated into the design.All VCO and loop filter components are integrated.The core of the AD9361 can be powered directly from a 1.3 Vregulator. The IC is controlled via a standard 4-wire serial portand four real-time input/output control pins. Comprehensivepower-down modes are included to minimize power consumptionduring normal use. The AD9361 is packaged in a 10 mm × 10 mm,144-ball chip scale package ball grid array (CSP_BGA).Applications Point to point communication systems Femtocell/picocell/microcell base stations General-purpose radio systems
