Maxim Integrated MAX2700

The MAX2700/MAX2701 are highly integrated direct downconversion (zero-IF) receivers designed for wideband wireless local loop (WLL) systems operating in the 1.8GHz to 2.5GHz band. The MAX2700/MAX2701s’ zero-IF architecture eliminates the need for IF downconversion stages and the use of an IF SAW filter. This reduces the overall receiver cost by reducing the component count and required board space.

GENERAL DESCRIPTION

FEATURES

o Input Frequency Range 1.8GHz to 2.1GHz (MAX2700) 2.1GHz to 2.5GHz (MAX2701) o Cascaded Performance at 1960 MHz 3.5dB Noise Figure -7.5dBm Input IP3 at Maximum Gain o LNA with Selectable Gain and Shutdown Option o High Linearity Direct I/Q Downconverter o Wideband LO Quadrature Generator o 3dB Baseband Channel Bandwidth of At Least 56MHz o Variable Gain Baseband Amplifiers with >60dB Control Range o Baseband Gain Offset Correction Loop o +2.7V to +3.3V Single-Supply Operation o Small 48-pin TQFP-EP Package MAX2700/MAX2701 The MAX2700/MAX2701 have three main blocks: lownoise amplifier (LNA), quadrature downconverter, and baseband variable gain amplifiers (VGAs). The LNA is a single-ended amplifier with selectable gain and shutdown options. It provides a high input third-order intercept point (IP3), which reduces cross-modulation and gain compression due to high-level RF interference. The quadrature downconverter section consists of two highly linear double-balanced mixers driven by an external local oscillator (LO) with a selectable LO doubler.
