摘要： The present invention relates to a microwave filter, having U-type resonators, which passes a desired frequency signal and removes an undesired frequency signal when used in a high frequency antenna circuit for wireless communication systems. In accordance with the trend of reducing communication system terminals, it is required to reduce a high frequency filter. The high frequency filter is required to attenuate signals very sharply at the stop band especially near to a passband transmitting and receiving frequency, so as to improve the efficiency of the frequency. The filter may be reduced in weight by forming U-type resonators instead of straight-type resonators. Excellent attenuation characteristics may be achieved at the stop band lower than the passband, using the difference of the characteristic impedance between the open end portion and the shorted portion of the resonator by forming the coupling control grooves at the outer walls of the dielectric block.
摘要翻译：本发明涉及一种具有U型谐振器的微波滤波器，当用于无线通信系统的高频天线电路中时，该滤波器通过期望的频率信号并去除非期望的频率信号。根据减少通信系统终端的趋势，需要降低高频滤波器。需要高频滤波器在阻带处非常清晰地衰减信号，特别是靠近通带发射和接收频率，以提高频率的效率。通过形成U型谐振器而不是直型谐振器，可以减小滤波器的重量。通过在介质块的外壁处形成耦合控制槽，可以通过使用谐振器的开口端部分和短路部分之间的特性阻抗的差异，在低于通带的阻带处获得优异的衰减特性。

摘要： A dielectric resonator includes a dielectric block having an open surface at one of the surfaces thereof, the remaining surfaces being plated with a conductor. The dielectric block has an inner conductor hole formed at a surface of the dielectric block opposite to the open surface, the inner conductor hole extending a predetermined depth toward the open surface such that it does not perforate through the open surface. An electrode pattern is formed on the open surface such that it faces an end surface of the inner conductor hole, the electrode pattern being adapted to provide an input/output capacitor. The dielectric block has a coupling window formed on a predetermined portion of one of the surfaces of the dielectric block, except for the open surface and the surface formed with the inner conductor hole, at a position adjacent to one of the open surface and the surface formed with the inner conductor hole. The coupling window is free of the plated conductor and adapted to control a coupling degree of the resonator to another resonator. Other embodiments include integral type filters having resonators in a single dielectric block.

摘要： A duplexer having dual coupled line characteristics is disclosed. With a small number of resonators and without using an external device such as a chip inductor or a chip capacitor, the signals of the receiving frequency can be improvingly damped. The diameters of the transmitting terminal dielectric filter resonators and the receiving terminal dielectric filter resonators are not same, but their diameters at an open terminal and at a short circuit terminal are made different from each other so as to differentiate a coupling amount at the short circuit terminal from that at the open terminal. Further, the transmitting terminal filter resonators and the receiving terminal dielectric filter resonator are provided in a form of grooves, and sizes of the grooves near the open terminal are made different from those of the grooves near the short circuit terminal so as to differentiate a coupling amount of the resonators at the short circuit terminal from those at the open terminal. The duplexer of the present invention is used in the transmission/receiving separate type filter of the mobile communication.
