General Description
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 -40°C to +85°C at 3V.
