摘要： A dielectric block includes a plurality of plated through holes each having an inner conductor formed thereon to form respective plated through holes. At least one of the plated through holes branches into two legs at the short circuit side thereof so that the two legs are close to the short circuit side of the plated through holes adjacent thereto. This allows the resonators formed of the plated through holes to be strongly inductively coupled with each other.

摘要： A dielectric filter and a dielectric duplexer have simple structures, in each of which the resonance frequency of a TE mode is controlled in such a manner that no TE-mode spurious response occurs in a band requiring attenuation. Specifically, the distance between the central position of each of inner-conductor-formed holes and a widthwise line of a dielectric block is set to be two times or more than the distance between the central position of each of the holes and a lengthwise line thereof. With this arrangement, the resonance frequency of a spurious mode such as a TE101 mode is shifted to the low-frequency side to deviate the resonance frequency of the spurious mode from a band requiring attenuation, for example, from a band near the second-order harmonic of a TEM mode, as a mode to be used. In addition, a communication apparatus is formed by using one of the filter and the duplexer described above.
摘要翻译：介质滤波器和介质双工器具有简单的结构，其中TE模式的谐振频率以这样的方式被控制，使得在需要衰减的频带中不发生TE模式杂散响应。具体地说，每个内导体形成的孔的中心位置和介质块的宽度方向之间的距离设定为每个孔的中心位置和其长度方向之间的距离的两倍或更多。利用这种布置，诸如TE101模式的寄生模式的谐振频率被转移到低频侧，以将杂散模式的谐振频率从需要衰减的频带偏离，例如，从接近二阶的频带谐波的TEM模式，作为使用的模式。此外，通过使用上述滤波器和双工器之一形成通信装置。

摘要： A dielectric duplexer contains a substantially-rectangular-parallelepiped-shaped dielectric block. The dielectric block includes plated through holes having inner conductors formed thereon. An outer conductor is formed on an exterior surface of the dielectric block. An input/output terminal is formed by an outer-conductorless portion separating the input/output terminal from the outer conductor of the plated through holes and is defined by an outer-conductorless portion extending from a short circuit face of the dielectric block to a mounting surface thereof. An antenna excitation hole is formed as a through-hole in the same axial direction as that of the plated through holes in the dielectric block. The antenna excitation hole contains an electrode which is coupled to the antenna terminal. Two electrodeless portions, each having a predetermined shape, are formed between open edges of two plated through holes and a top face of the dielectric block.

摘要： In an acoustic wave filter, first and second filter elements are connected between an unbalanced terminal and first and second balanced terminals on an acoustic wave substrate. The filter elements are longitudinally-coupled surface wave filters including at least three IDTs. One end of the IDTs is mutually connected and is connected to the unbalanced terminal. The other ends of the IDTs are connected by a second connecting line so as to define an unbalanced-side grounded portion. Grounded ends of the IDTs are connected to each other by a first connecting line so as to define a common midpoint grounded portion. The common midpoint grounded portion and the unbalanced-side grounded portion are electrically separated from each other.
