摘要： High frequency packages have a plurality of apertures (notches) as antennas, and each of these apertures possesses a specific resonance frequency that may exist within the frequency bandwidth used in the high frequency packages in a high frequency band. Thus, the resonance frequency produced within the package is shifted outside the frequency bandwidth. A high frequency package is provided with a metal frame disposed on a metal bottom plate and having apertures for connecting with external terminals, dielectrics being disposed on the bottom metal plate, and on which a high frequency transmission line and a plurality of input and output terminals are formed, microwave circuitry being contained in the metal frame, and a metal lid, wherein the frequency of the aperture's resonance arising from electromagnetic field between the metal frame and the metal bottom plate, is shifted outside the frequency bandwidth by diminishing and optimizing the width of the aperture.

摘要： A bandstop filter where variation in characteristics is suppressed to minimum and which realizes an increased production yield. The physical length of a line joint portion between a main line and an oscillator can be enlarged by providing an impedance non-continuous structure portion in a strip conductor of the oscillator. In comparison to the case where the impedance non-continuous structure portion is not provided, the width of a joint slit required to obtain an equal joint amount can be enlarged. When the joint slit width is enlarged, variation in filter characteristics caused by pattern accuracy can be reduced because of the enlarged joint slip width, thus improving a filter yield. This means that pattern accuracy requirement for production is loosened. Freedom in selecting a dielectric substrate is increased, which also provides an advantage that a filter can be produced using a less expensive dielectric substrate with not very high pattern accuracy.
摘要翻译：将特性变化抑制到最小的带阻滤波器，实现增加的产量。通过在振荡器的带状导体中提供阻抗不连续的结构部分，可以扩大主线和振荡器之间的线接合部分的物理长度。与没有设置阻抗非连续结构部的情况相比，可以扩大获得相等接合量所需的接缝的宽度。当接缝宽度扩大时，由于关节滑移宽度的增大可以减小图案精度引起的过滤器特性的变化，从而提高过滤器的收率。这意味着生产的图形精度要求被放宽了。提高了选择电介质基板的自由度，这也提供了利用不太高图案精度的较便宜的电介质基板来制造滤光片的优点。
