MAX2742 Single-Chip Global Positioning System Receiver Front-End

Description

The MAX2742 complete single-chip global positioning system (GPS) RF front-end utilizes many innovative and leading-edge RF CMOS design techniques. This high-performance, state-of-the-art device consumes extremely low power and eliminates the need for costly SAW and bulky discrete IF filters. The MAX2742 incorporates a fully integrated low-noise amplifier (LNA) and mixer, IF section, digital sampler, and local oscillator synthesizer.

The intended input signal for the MAX2742 is the L1 GPS signal 1.57542GHz. This device supports high-accuracy output quantization, which delivers the best performance obtainable for the GPS receiver. The power consumption of the MAX2742 is as low as 32mW at a +2.4V supply.

The MAX2742 is available in a space-saving 48-pin TQFP package and is specified for the extended (-40°C to +85°C) temperature range.
