APPARATUS FOR MEASURING VOLTAGE STANDING WAVE RATIO OF RADIO FREQUENCY

摘要

PURPOSE: An apparatus for measuring the voltage standing wave ratio of a radio frequency is provided to measure a factor lowering the quality of call by measuring the real-time voltage standing wave ratios by paths. CONSTITUTION: A reference signal generator(311) generates a reference signal used to measure the voltage standing wave ratio of a receiving path. A signal distributor(312) distributes the voltage standing wave ratio measuring reference signals transported from the reference signal generator(311) and transfers them to a receiving terminal. A delay device(313) delays the signals reflected and transported from a transmitting path and the receiving path as much as a preset time. A power measurer(314) measures the power of the signals transported from the delay device(313). A voltage standing wave ratio measurer(315) measures the voltage standing wave ratio of the transmitting path and the receiving path using the power values measured by the power measurer(314).
