High-frequency low-pass filter.

摘要

A high-frequency low-pass filter includes a first dielectric layer (12). A second dielectric layer (18), a third dielectric layer (26), a fourth dielectric layer (32), and a fifth dielectric layer (38) are laminated on the first dielectric layer (12). An earth electrode (14) is formed on the first dielectric layer (12). A first capacitive open-circuited stub electrode (20) , a second capacitive open-circuited stub electrode (22) and a third capacitive open-circuited stub electrode (24) are formed on the second dielectric layer (18). A first strip line electrode (28) and a second strip line electrode (30) are formed on the third dielectric layer (26). The first and second strip line electrodes are formed as meander lines. A shield electrode (34) is formed on the fourth dielectric layer (32).
