GP2010

GPS Receiver RF Front End

Supersedes edition in August 1996 Global Positioning Products Handbook, HB4305-1.0

DS4056 - 3.4 October 1996

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.
