Abstract

Abstract Translated from Japanese (57)【要約】 【目的】小型化され、実装したときの占有面積が小さな 誘電体フィルタを提供する。 【構成】誘電体層12上に共振素子の一部を構成する共 振線路21aおよび21bを形成する。誘電体層12上 に積層される誘電体層13上に内部アース電極30を形 成する。誘電体層13上に積層される誘電体層14上に 共振素子の一部を構成する共振線路21bおよび22b を形成する。共振線路21bの前端部および共振線路2 1aの前端部が内部に導体が充填されたビアホール91 によって接続されて入力側の1/4波長型ストリップラ イン共振素子を構成し、共振線路22bの前端部および 共振線路22aの前端部が内部に導体が充填されたビア ホール92によって接続されて出力側の1/4波長型ス トリップライン共振素子を構成する。 (57) [Abstract] [Purpose] To provide a dielectric filter that is downsized and occupies a small area when mounted. [Structure] Resonant lines 21a and 21b forming a part of a resonant element are formed on a dielectric layer 12. An internal ground electrode 30 is formed on the dielectric layer 13 laminated on the dielectric layer 12. Resonant lines 21b and 22b forming a part of a resonant element on the dielectric layer 14 laminated on the dielectric layer 13. To form. The front end of the resonance line 21b and the resonance line 2 Via hole 91 in which the front end of 1a is filled with a conductor inside To form a 1/4 wavelength type stripline resonance element on the input side, and the front end of the resonance line 22b and the front end of the resonance line 22a are connected by a via hole 92 filled with a conductor inside and are connected to the output side. A 1/4 wavelength stripline resonant element is constructed.
