The GP2015 is a GPS receiver RF front-end circuit which provides a low- power, low-cost and high reliability GPs RF front-end solution. With the same performance of GP2010, GP2015 uses TQFP-48 package, 3V to 5V operating supply voltage, 200mW (3V voltage) power consumption. Ll (1575.42MHz) C / A (Coarse-Acquisition) code signal is input to GP2015 by the antenna and low noise amplifier to output is a 2bit digital signal. The GP2015 includes an on-chip synthesizer, mixer, automatic gain control (AGC), and a quantizer which can provide sign and magnitude digital output. A complete GPS receiver RF front-end circuit only requires minimal external components.
