发明名称 RADIO FREQUENCY RECEPTION CIRCUIT FOR MOBILE PHONE
摘要 An RF (Radio Frequency) receiving apparatus and method of a mobile communication terminal are disclosed to perform a GPS signal receiving function for a position tracking service. The RF receiving apparatus includes a first CDMA RF matching unit for RF-matching a CDMA signal without a change in a power strength and a second CDMA RF matching unit for RF-matching a CDMA signal while reducing a power strength. When a position tracking service is requested, one of the first CDMA RF matching unit and the second CDMA RF matching unit is selected as an RF matching path of the CDMA signal according to the power strength of the received CDMA signal. Thus, with interference/influence of the CDMA signal minimized, a GPS signal is received and thus a satellite search performance of the mobile communication terminal is enhanced. <IMAGE>
