MAX2310
MAX2310 is CDMA IF VGAs and I/Q Demodulators manufactured by Maxim Integrated.
Description
The MAX2310/MAX2312/MAX2314/MAX2316 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 dynamic range of over 110d B, and high input IP3 (-33d Bm at 35d B gain, 1.7d Bm at -35d B).
Unlike similar devices, the MAX2310 family of receivers includes dual oscillators and synthesizers to form a self-contained IF subsystem. The synthesizer’s reference and RF dividers are fully programmable through a 3-wire serial bus, enabling dual-band system architectures using any mon reference and IF frequency. The differential baseband outputs have enough bandwidth 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-controlled oscillator (VCO) and synthesizer, the MAX2310 draws only 26m A from a +2.75V supply in CDMA (differential IF) mode.
The MAX2310/MAX2312/MAX2314/MAX2316 are available in 28-pin QSOP packages.
