GPS RFIC


GPS RFIC is a low cost CMOS low-IF GPS receiver. It covers all RF circuitry needed for a robust, high performing GPS receiver. It includes on-chip low noise LNA, a mixer down converting and analog baseband supporting 2/3 bits signed magnitiude output. The chip integrates a fractional-N PLL with on-chip XO supporting all GSM crystals from 10 to 52 MHz. Supported with a powerful power management unit guaranteeing operation at the lowest possible power, and based on 65nm technology, our GPS is the most optimum solution in the market for cellular devices.
