The AD9363 is a high performance, highly integrated RF agiletransceiver designed for use in 3G and 4G femtocell applications.Its programmability and wideband capability make it ideal for abroad range of transceiver applications. The device combines anRF front end with a flexible mixed-signal baseband section andintegrated frequency synthesizers, simplifying design-in byproviding a configurable digital interface to a processor. TheAD9363 operates in the 325 MHz to 3.8 GHz range, coveringmost licensed and unlicensed bands. Channel bandwidths fromless than 200 kHz to 20 MHz are supported.

The two independent direct conversion receivers have state-of-the-artnoise figure and linearity. Each 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 AD9363also has flexible manual gain modes that can be externallycontrolled. Two high dynamic range ADCs per channel digitizethe received I and Q signals and pass them through configurabledecimation filters and 128-tap finite impulse response (FIR)filters to produce a 12-bit output signal at the appropriatesample rate.

The transmitters use a direct conversion architecture that achieveshigh modulation accuracy with ultralow noise. This transmitterdesign produces a best-in-class Tx EVM of −34 dB, allowingsignificant system margin for the external power amplifier (PA)selection. The on-board Tx power monitor can be used as apower detector, enabling highly accurate Tx powermeasurements.

The fully integrated phase-locked loops (PLLs) provide lowpower fractional N frequency synthesis for all receive andtransmit channels. Channel isolation, demanded by FDDsystems, is integrated into the design. All voltage controlledoscillators (VCOs) and loop filter components are integrated.The core of the AD9363 can be powered directly from a 1.3 Vregulator. The IC is controlled via a standard 4-wire serial portand four real-time I/O control pins. Comprehensive power-downmodes are included to minimize power consumption duringnormal use. The AD9363 is packaged in a 10 mm × 10 mm,144-ball chip scale package ball grid array (CSP_BGA).
