Abstract:
1. An RF receiving apparatus of a mobile communication terminal comprising: a controller for controlling a switching operation of an RF matching path of a signal; and a switch controlled by the controller for switching the signal between a first RF matching unit and a second RF matching unit; the first RF matching unit RF-matching the signal; the second RF matching unit RF-matching the signal; wherein the controller checks a power strength of the signal and compares the power strength of the signal to a reference power strength, wherein if the power strength of the signal is larger than the reference power strength, the controller outputs a first switching control signal to the switch for switching the signal to the second RF matching unit; wherein the reference power strength is set at a level at which the signal interferes with GPS RF reception performance; wherein the first RF matching unit comprises a first PCB line connected in series to a first output of the switch and having a first characteristic impedance, and the second RF matching unit comprises a second PCB line connected in series to a second output of the switch and having a second characteristic impedance, wherein the second characteristic impedance is greater than the first characteristic impedance.
