ADI AD9363ABCZ

The AD9363 is a high performance, highly integrated RF agile transceiver designed for use in 3G and 4G femtocell applications. 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 AD9363 operates in the 325kHz to 3.8GHz range, covering most licensed and unlicensed bands. Channel bandwidths from less than 200kHz to 20MHz are supported.

The two independent direct conversion receivers have state- of- the- art noise figure and linearity. Each 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 AD9363 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 configurable decimation filters and 128- tap finite impulse response (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 - 34dB allowing significant system margin for the external power amplifier (PA) selection. The on- board 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 FDD systems, is integrated into the design. All voltage controlled oscillators (VCOs) and loop filter components are integrated.

The core of the AD9363 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 AD9363 is packaged in a 10mm×10mm 144- ball chip scale package ball grid array (CSP_BGA).
