GENERAL DESCRIPTION
The AD9361 is a high performance, highly integrated RF Agile
Transceiver™ designed for use in 3G and 4G base station applica-
tions. Its programmability and wideband capability make it
ideal for a broad range of transceiver applications. The device
combines an RF front end with a flexible mixed-signal baseband
section and integrated frequency synthesizers, simplifying
design-in by providing a configurable digital interface to a
processor. The AD9361 operates in the 70 MHz to 6.0 GHz
range, covering most licensed and unlicensed bands. Channel
bandwidths from less than 200 kHz to 56 MHz are supported.
The two independent direct conversion receivers have state-of-
the-art noise figure and linearity. Each receive (RX) subsystem
includes independent automatic gain control (AGC), dc offset
correction, quadrature correction, and digital filtering, thereby
eliminating the need for these functions in the digital baseband.
The AD9361 also has flexible manual gain modes that can be
externally controlled. Two high dynamic range ADCs per channel
digitize the received I and Q signals and pass them through con-

figurable decimation filters and 128-tap FIR filters to produce
a 12-bit output signal at the appropriate sample rate.
The transmitters use a direct conversion architecture that
achieves high modulation accuracy with ultralow noise. This
transmitter design produces a best in class TX EVM of <−40 dB,
allowing significant system margin for the external PA selection.
The on-board transmit (TX) power monitor can be used as a
power detector, enabling highly accurate TX power measurements.
The fully integrated phase-locked loops (PLLs) provide low
power fractional-N frequency synthesis for all receive and
transmit channels. Channel isolation, demanded by frequency
division 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 V
regulator. The IC is controlled via a standard 4-wire serial port
and four real-time I/O control pins. Comprehensive power-down
modes are included to minimize power consumption during
normal use. The AD9361 is packaged in a 10 mm × 10 mm,
144-ball chip scale package ball grid array (CSP_BGA).
