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 operation in hostile RFI environments found in cellular base stations. The MAX2740 also includes a high-performance voltage-controlled oscillator (VCO) with low phase noise for subcentimeter carrier phase applications, 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 provide a cost-effective and high-performance solution for navigation and timing products that need maximum satellite availability. |
