General Description
The MAX2740 is a complete global positioning system
(GPS) receiver from antenna output to digitizer input.
The signal path includes the LNA, two downconverters,
and variable-gain and fixed-gain amplifiers. By utilizing
a double-conversion superheterodyne architecture with
external surface acoustic wave (SAW) filters, high levels
of image rejection and blocking immunity are possible.
Receiver linearity has been maximized to improve oper-
ation in hostile RFI environments found in cellular base
stations. The MAX2740 also includes a high-perfor-
mance voltage-controlled oscillator (VCO) with low
phase noise for subcentimeter carrier phase applica-
tions, and a fixed-frequency synthesizer for generation
of all required on-chip local oscillators.
The unique frequency plan captured in the MAX2740 is
suitable for joint GPS/GLONASS receivers with minimal
external components. This allows the MAX2740 to pro-
vide a cost-effective and high-performance solution for
navigation and timing products that need maximum
satellite availability.
The MAX2740 is compatible with a high-performance
DSP engine capable of very fast time to first fix and
excellent multipath rejection.
