Description

The GP2010 is Mitel Semiconductor second generation RF Front-end for Global Positioning System (GPS) receivers. The GP2010 uses many innovative design techniques and a leading-edge bipolar process to offer a low power, low cost and high reliability RF Front End solution . The GP2010 is designed to operate from either 3 or 5 Volt power supplies.

The input to the device is the L1 (1575.42MHz) Coarse- Acquisition (C/A) code Global Positioning signal from an antenna (via a low-noise pre-amplifier). The output is 2-bit quantised for subsequent signal processing in the digital domain. The GP2010 contains an on-chip synthesiser, mixers, AGC and a quantiser which provides Sign and Magnitude digital outputs. A minimum of external components is required to make a complete GPS front-end.

The GP2010 has been designed to operate with the GP2021 12-channel Global Positioning Correlator, and DW9255 SAW filter, both also available from Mitel Semiconductor.
