MAX2741 Integrated L1-Band GPS Receiver

The MAX2741 L1-band GPs receiver IC offers a high-performance, compact solution for mobile handsets, PDAs, and automotive applications. Total voltage gain of 80dB and a 4.7dB cascaded noise figure CAN pro-vide receiver sensitivity for applications requiring -185dBW for indoor tracking solutions.
This dual-conversion receiver downconverts the 1575.42MHz GPs signal to a 37.38MHz first IF, and then a 3.78MHz second IF. An integrated 2- or 3-bit ADC (1- bit SIGN, 1- or 2-bit MAG selectable) samples the sec-ond IF and outputs the digitized signals to the baseband processor.
The integrated synthesizer offers the flexibility in fre-quency planning to allow a single board design to be employed for reference frequencies from 2MHz to 26MHz. The integrated reference Oscillator allows either TCXO or crystal operation.
The receiver runs from a 2.7V to 3.0V supply, and draws only 30mA when active. It is offered in a 28-pin thin QFN package, and is specified for -40C to +85C at 3V.
