Title: Method for over power limit implement of linear power amplifier in mobile communication system
Inventor: JUNG CHANG JIN
IPC: H04W52/14
Filed: 2002-09-30
Abstract: PURPOSE: A method for implementing an over-power limit of an LPA(Linear Power Amplifier) in a mobile communication system is provided to measure when an output power exceeds a set threshold value from a BTU(BTS Test Unit), and to attenuate the power through a variable attenuator of an up converter located on a front end of an LPA, thereby protecting the LPA. CONSTITUTION: A system turns on an over-power limit mode of an LPA(ST11), and sets an over-power threshold value preventing an LPA shutdown(ST12). A BTU measures an output power of the LPA in real time(ST13). The BTU compares the measured output power with the set threshold value(ST14). If the output power exceeds the threshold value, the BTU generates an over-power alarm, and reports the alarm to a BCP(BTS Control Processor)(ST15). The BCP attenuates the power by operating a variable attenuator of an up converter(ST16). The BCP compares the output power with the threshold value(ST17). If the power is smaller than the threshold value, the BCP releases an attenuation value(ST18), and compares the output power with the threshold value(ST19). The BCP repeats the releasing process(ST20,ST21). If the output power is still smaller than the threshold value after releasing the attenuation value, the BTU clears the alarm and returns to the initial step(ST22).
