DIELECTRIC PORCELAIN FOR HIGH-FREQUENCY REGION, DIELECTRIC RESONATOR, DIELECTRIC FILTER, DIELECTRIC DUPLEXER AND TRANSMITTER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide dielectric porcelain for high-frequency regions which is suitable as dielectric porcelain included in a dielectric resonator, and in which arbitrary electrical properties are easily given and the adhesion strength of a plated film is increased.;SOLUTION: The dielectric porcelain for high-frequency regions comprises a mixture of first porcelain which gives an adhesion strength of a plated film of ≥70 (N/2×2 mm) and second porcelain which gives an adhesion strength of a plated film of 70 (N/2×2 mm). Here, the first porcelain (A) and the second porcelain (B) are mixed in a volume fraction represented by the formula: 10≤{A/(A+B)}×100100.;COPYRIGHT: (C)2003,JPO
