Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX2742 complete single-chip global positioning system (GPS) RF front-end utilizes many innovative and leading-edge RF CMOS design techniques. This highperformance, 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 highaccuracy 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.
