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