MAX2306 - CDMA IF VGAs and I/Q Demodulators

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.

Key Features

MAX2306/MAX2308/MAX2309 19-2014; Rev 3; 8/04 EVALUATION KIT AVAILABLE CDMA IF VGAs and I/Q Demodulators with VCO and Synthesizer 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.
