The MAX2306/MAX2308/MAX2309 a re IF re c e ive rs

designed for dual-band, dual-mode, and single-mode

N-CDMA and W-CDMA cellular phone systems. The

signal path consists of a variable-gain amplifier (VGA)

and I/Q demodulator. The devices feature guaranteed

+2.7V operation, a gain control range of over 110dB,

and high input IP3 (-31dBm at 35dB gain, 3.4dBm at

-35dB gain).

♦ Complete IF Subsystem Includes VCO and

Synthesizer

♦ Supports Dual-Band, Triple-Mode Operation

♦ VGA with >110dB Gain Control

♦ Quadrature Demodulator

♦ High Output Level (2.7V)

Unlike similar devices, the MAX2306 family of receivers

includes dual oscillators and synthesizers to form a

self-contained IF subsystem. The synthesizer’s refer-

ence and RF dividers are fully programmable through a

3-wire serial bus, enabling dual-band system architec-

tures using any common reference and IF frequency.

The differential baseband outputs have enough band-

width to suit both N-CDMA and W-CDMA systems, and

offer saturated output levels of 2.7Vp-p at a low +2.75V

supply voltage. Including the low-noise voltage-con-

trolled oscillator (VCO) and synthesizer, the MAX2306

draws only 26mA from a +2.75V supply in CDMA (dif-

ferential IF) mode.

♦ Programmable Charge-Pump Current

♦ Supports Any IF Frequency Between 40MHz and

300MHz

♦ 3-Wire Programmable Interface

♦ Low Supply Voltage (+2.7V)
