FREQUENCY PHASE CONTROL SYSTEM

摘要

PURPOSE: A frequency phase control system used for a wireless communication system is provided to obtain a desired phase control valve even at a frequency bandwidth lower than 500MHz by providing a U-shaped conductive tube. CONSTITUTION: The frequency phase control system comprises an I/O connector for inputting and outputting a signal; U-shaped inner and outer conductive tubes(24, 22), the inner and outer conductive tubes(24,22) are inserted into one another to function as a taper track(33) for varying phase by varying an electrical length; an actuator for moving the inner conductive tube; and a locking device(48) for fixing the actuator.
