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.
