摘要： A band-pass filter functioning as a electronic chip component includes a chip having upper and lower surfaces, a pair of side surfaces, and first and second end surfaces facing each other. A resonator electrode is disposed in the chip. The band-pass filter also includes input and output electrodes extending in the vertical direction, which are coupled or connected to the resonator electrode, and a tubular first ground electrode surrounding the chip so as to enclose the resonator electrode. The input and output electrodes are disposed at end portions or inner sides of the tubular portion so as not to be electrically connected to the first ground electrode. The band-pass filter further includes two pairs of second ground electrodes which are disposed on both sides of the input electrode and/or output electrode and which are electrically connected to the first ground electrode.

摘要： A dual-mode band-pass filter is provided which can be reduced in size and has a high design flexibility.
The dual-mode band-pass filter has a frame-shaped electrode pattern (23) formed on one face or inside a dielectric substrate. A pair of input-output circuits (5, 6) are coupled to the frame-shaped electrode pattern (23). The plane shape and the line-width of the frame-shaped electrode pattern (23) is configured so that two generated resonance modes can be coupled to each other.摘要翻译： 提供了双模式带通滤波器，其可以减小尺寸并具有高设计灵活性。 双模带通滤波器具有形成在电介质基板的一个面或内部的框状电极图案（23）。 一对输入输出电路（5,6）被耦合到框状电极图案（23）。 框状电极图案（23）的平面形状和线宽被配置为使得两个产生的共振模式能够彼此耦合。
