The MAX2310/MAX2312/MAX2314/MAX2316 are IF

receivers designed for dual-band, dual-mode, and sin-

gle-mode N-CDMA and W-CDMA cellular phone sys-

tems. The signal path consists of a variable gain

amplifier (VGA) and I/Q demodulator. The devices fea-

ture guaranteed +2.7V operation, a dynamic range of

over 110dB, and high input IP3 (-33dBm at 35dB gain,

1.7dBm at -35dB).

Unlike similar devices, the MAX2310 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 MAX2310

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

ferential IF) mode.

The MAX2310/MAX2312/MAX2314/MAX2316 are avail-

able in 28-pin QSOP packages.
