    • A high-frequency circuit element including a substrate, a high-frequency circuit formed on the substrate, a metal box electromagnetically shielding the high-frequency circuit by enclosing the substrate and an input/output terminal placed on the metal box and inputting/outputting a high-frequency signal to/from the high-frequency circuit. Adding at least one plate for interrupting unwanted higher-order mode cutting off the propagation path of the high frequency waves in the space inside the metal box by substantially dividing the space inside the metal box makes it possible to cut off the propagation path where the high frequency waves propagates in the space inside the box and to suppress excitation and propagation of the unwanted higher-order mode that adversely affects the frequency characteristic of the high frequency circuit element.
    • 一种高频电路元件,包括基板,形成在基板上的高频电路,通过封装基板电磁屏蔽高频电路的金属盒和放置在金属盒上的输入/输出端子,以及输入/输出 高频信号往/从高频电路。 添加至少一块用于中断不需要的高阶模式的板,通过基本上划分金属盒内部的空间来切断金属盒内的空间中的高频波的传播路径,使得可以切断传播路径,其中高 频率波在箱内的空间中传播,并且抑制不利地影响高频电路元件的频率特性的不需要的高阶模式的激励和传播。
