GENERAL DESCRIPTION

The AD9352-5 is a fully integrated transceiver for IEEE 802.16

WiMAX wireless network systems. The RF MxFE® combines

the RF front end with mixed-signal baseband enabling and

easy-to-use digital interface to the baseband ASIC or FPGA.

The AD9352-5 operates in the 4.9 GHz to 6.0 GHz range

covering most of the licensed and unlicensed bands. Channel

bandwidths of 3.5 MHz, 4.375 MHz, 5 MHz, 7 MHz, 8.75 MHz,

10 MHz, 14 MHz, 17.5 MHz, and 20 MHz are supported.

The direct-conversion receiver has state-of-the-art noise figure

and linearity and requires no external components except a

balun. The complete RF subsystem integrates an autonomous

AGC loop and dc offset corrections, thus eliminating the need

for high speed interaction with the baseband processor. The

received signal strength indicator (RSSI) has over 80 dB of

dynamic range with 0.5 dB resolution and is accessible via the

serial interface.

The received signal is digitized with a high dynamic range

12-bit ADC. Decimation and channel filters produce a 10-bit

output signal at the appropriate sample rate determined by the

bandwidth mode. The transmit path takes 10-bit input data and

interpolates it before converting it to the analog domain and

upconverting it to the carrier frequency.

The highly linear transmit path has excellent spectral purity

with sideband noise less than −134 dBm/Hz at 22 MHz offset

and offers an EVM of −33 dB at 0 dBm output power.

The reference frequency is produced by an internal crystal

oscillator with digital programmable frequency with 0.012 ppm

resolution, thus reducing the total bill of materials of the device.

An internal auxiliary ADC and two auxiliary DACs are

available for system monitoring and control. Three general-

purpose I/Os are also included and can be register programmed

or automatically sequenced by a user-defined state machine.

Mode control is available via a 4-wire serial port and four real-

time I/O control pins.

The AD9352-5 is powered from a single 3.3 V supply and

contains on-chip LDOs for each function to eliminate external

regulators. The AD9352-5 is packaged in a 9 mm × 9 mm,

64-lead LFCSP.
