Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 LC共振器のインダクタンスが大きく、か つ、優れたQ特性を有する積層型LCフィルタを得る。 【解決手段】 インダクタパターン54a,54bは同 一形状であり、シート52を介して積層され、2重構造 のインダクタL1を構成する。同様に、インダクタパタ ーン55a,55bも、2重構造のインダクタL2を構 成する。コンデンサパターン58a,58bは、インダ クタパターン54a,54bの幅広部56a,56bに 対向し、コンデンサC1を形成する。同様に、コンデン サパターン59a,59bは、インダクタパターン55 a,55bの幅広部57a,57bに対向し、コンデン サC2を形成する。結合コンデンサパターン62はイン ダクタパターン54a,55aと54b,55bとの間 に位置する。 (57) [Problem] To provide a laminated LC filter having a large inductance of an LC resonator and excellent Q characteristics. SOLUTION: Inductor patterns 54a and 54b have the same shape and are stacked via a sheet 52 to form a double-structured inductor L1. Similarly, the inductor patterns 55a and 55b also constitute a double-structured inductor L2. The capacitor patterns 58a and 58b face the wide portions 56a and 56b of the inductor patterns 54a and 54b, and form a capacitor C1. Similarly, the capacitor patterns 59a and 59b are A capacitor C2 is formed opposite to the wide portions 57a and 57b of a and 55b. The coupling capacitor pattern 62 is located between the inductor patterns 54a, 55a and 54b, 55b.
