General Description
The MAX2306/MAX2308/MAX2309 are IF receivers
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).
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.
The MAX2306/MAX2308/MAX2309 are available in 28-
pin QFN packages.
