    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 reference and RF dividers are fully programmable through a 3-wire serial bus, enabling dual-band system architectures using any common 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 MAX2306 draws only 26mA from a +2.75V supply in CDMA (differential IF) mode.

    The MAX2306/MAX2308/MAX2309 are available in 28-pin QFN packages.

    Features and Benefits

    • Dual Oscillators (MAX2306)
    • On-Board PLL Synthesizer
    • 3-Wire Interface
    • Single-Ended or Differential Baseband Outputs
    • +2.7V to +5.5V Single-Supply Operation
    • SMA Connectors on All Signal Ports
    • PC Control Software (available at www.maximintegrated.com)

    Product Detail

    The MAX2306/MAX2308/MAX2309 evaluation kits (EV kits) simplify testing of the MAX2306/MAX2308/ MAX2309 IF receivers. These kits allow evaluation of the devices' variable-gain amplifier (VGA), I/Q demodulator, dual-band voltage-controlled oscillators (VCOs), synthesizer, 3-wire programming interface, and power-management features.

    The EV kits provide 50Ω SMA connectors for all signal inputs and outputs. A varactor-based tank circuit is provided for the on-chip VCO and can be tuned by a potentiometer or an external voltage or phase-locked with the on-chip phase-locked loop (PLL).
