GP2015

GP2015 GPS Receiver RF Front End Supersedes edition in August 1996 Global Positioning Products Handbook, HB4305-1.0 DS4374 - 2.4 October 1996 The GP2015 is a small format RF Front-end for Global Positioning System (GPS) receivers. Equivalent in performance to the GP2010 but in a TQFP package, this product is suited for size-critical applications as the RF area can be reduced by a factor of two to three using miniature surface mount passive components The GP2015 is designed to operate from either 3 or 5 Volt supplies. The input to the device is the L1 (1575.42MHz) CoarseAcquisition (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 GP2015 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 device has been designed to operate with the GP2021 12-channel Global Positioning Correlator, and DW9255 SAW filter, both also available from Mitel Semiconductor.
