COAXIAL RESONATOR

摘要

FIELD: filters of couplers for cellular communication. SUBSTANCE: device has rectangular chamber which has conducting element (central conductor) which is designed as oval plate. Central conductor and oval plate are moved in rectangular chamber in order to tune main frequency of resonator. In addition device has tuning element which is located near plate of central conductor and is shaped as H-beam which rotates with shaft which is connected to step motor. Rotation of H-beam element provides frequency tuning of coaxial resonator. EFFECT: increased functional capabilities. 12 cl, 2 dwgc
