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) 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 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.
