CIRCUIT FOR MEASURING THE TRANSMISSION POWER AND THE TRANSMISSION AND RECEIVE STANDING WAVE RATIO OF STATION IN MOBILE COMMUNICATION SYSTEM

摘要

A transmitting and receiving antenna VSWRs (voltage standing wave ratio) measuring circuit of a base station in a mobile communication system comprises: transmitting and receiving antennas for transmitting and receiving a radio frequency signal of a predetermined frequency band in a mobile communication system; transmitting antenna VSWR measuring means for variable-attenuating and detecting a transmitting signal received from the transmitting antenna and sending a transmitting signal strength to a measuring controller whereby to measure transmitting power and reflected power; and receiving antenna VSWR measuring means for variable-attenuating and detecting a receiving signal received from the transmitting antenna and sending a receiving signal strength to a measuring controller whereby to measure receiving power and reflected power.
