General 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 extreme-
ly 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
