Coaxial type filter

Abstract

Abstract PURPOSE: To make a filter small-size, make adjustment needless for the filter and improve a vibration-proof property by using a dielectric substrate in inter-step connection parts in the filter constitution. CONSTITUTION: Dielectric substrate 500 provided to support one ends of plural resonance circuit elements 47 to 49 is provided, and conductor regions are formed on one face or both faces of this substrate 500 correspondingly to elements 47 to 49 and are matched to inter-step connections, and shielding plates 34 and 35 are provided between elements 47 to 49. As a result, the filter can be made small-size, and no adjustment is required for the filter, and the vibration-proof property can be improved. COPYRIGHT: (C)1980,JPO&Japio
