Abstract

The invention discloses a device and a method for receiving global positioning system (GPS) signals in a mobile communication terminal. The method for receiving a Global Positioning System (GPS) signal in a multi-mode mobile communication terminal equipped with a GPS antenna includes the steps of: receiving a GPS signal from a GPS satellite via a GPS antenna; impedance matching the received GPS signal; correcting attenuation and reducing impedance Noise of a matched signal; passing only a signal of a predetermined frequency band among high-frequency signals; amplifying the passed signal.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2004-0091380 filed on November 10, 2004, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to mobile communication terminals, and more particularly, to a receiver device for reducing the noise figure (NF) of a multi-mode mobile communication terminal using a Global Positioning System (GPS) antenna. Background technique [0003] Generally, Code Division Multiple Access (CDMA) terminals capable of performing GPS functions using satellites have been designed to support not only Digital Cellular Network (DCN) with 800MHz band, Korean Personal Communications Service (PCS) with 1.8GHz, and At least one of the US PCS also supports GPS having a frequency band of 1.5 GHz. [0004] The above-mentioned CDMA terminals are classified into dual-band terminals equipped with DCN and GPS or PCS and GPS, and triple-band terminals equipped with DCN, PCS...
