MAX2310/MAX2312/MAX2314/MAX2316 CDMA IF VGAs and I/Q Demodulators with VCO and Synthesizer

PublishTime：2021-06-21

●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 l/Q demodulator. The devices feature guaranteed +2.7V operation, a dynamic range of over HOdB, and high input IP3 (-33dBm at 35dB gain, 1.7dBmat-35dB).
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 common referenee 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 2.7V-p-p at a low +2.75V supply voltage. Including the low-noise voltage-controlled 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 available in 28-pin QSOP packages.
