摘要： A dielectric duplexer has first and second filters passing two adjacent bands and is not influenced by signals in bands that are outwardly adjacent to the two passing bands. The space between small sectional area portions on short-circuit-end sides of first and second resonator holes is arranged to be relatively small, and the two resonator holes are coupled with each other according to a distributed-constant-type inductive coupling method. The space between small sectional area portions on short-circuit-end sides of fourth and fifth resonator holes is arranged to be relatively large, and the two resonator holes are coupled with each other according to a distributed-constant-type capacitive coupling method. Furthermore, the space between small sectional area portions on short-circuit-end sides of the fifth resonator hole and a sixth resonator hole is arranged to be relatively small, and the two resonator holes are coupled with each other according to a distributed-constant-type inductive coupling method. In this way, an attenuation pole is generated on a high-band side of a transmitting band according to the first and second resonator holes. Also, attenuation poles are individually generated on a high-band side and a low-band side of a receiving band according to the fourth, fifth, and sixth resonator holes.

摘要： A dielectric filter that can generate many more attenuation poles as well as attenuation poles generated by tap couplings so that arbitrary passing characteristics and attenuation characteristics can be obtained. In this filter, inside a dielectric block (1) there are formed through-holes (2a,2b) having stepped structures in which inner conductors are disposed on the inner surfaces of the holes to capacitively couple resonators (4a,4b). There are also formed lateral holes having conductive films disposed on the inner surfaces of the holes (5a,5b). The lateral holes (5a,5b) are connected to input/output terminals (7a,7b) in predetermined positions of the inner conductors (4a,4b). With this arrangement, attenuation poles are generated by both distributed constant resonator coupling and tap couplings on the low frequency side and high frequency side of a pass band.

摘要： PURPOSE: To provide a dielectric filter that controls resonance frequency in a TE mode so as not to cause a spurious response in the TE mode into a frequency band to be attenuated, without making the structure complicated and to provide a dielectric duplexer and a communication unit using them. CONSTITUTION: A distance B from the center of each of inner conductor forming holes 2a, 2b to a short side of a dielectric block is decided to be a double of a distance A from the center to a long side or larger. Thus, a resonance frequency in a spurious mode, such as a TE101 mode, is shifted toward a lower frequency band so as to cause the resonance frequency to shift in the spurious mode from a frequency band requiring attenuation, such as around a second order higher harmonic wave band in a TEM mode that is an operating mode.
摘要翻译：目的：提供一种在TE模式下控制谐振频率的介质滤波器，以便不使TE模式中的寄生响应进入要衰减的频带，而不会使结构复杂化，并提供介质双工器和通信单元使用它们。构成：从内导体形成孔2a，2b的每一个的中心到介质块的短边的距离B被决定为从中心到长边或更长边的距离A的两倍。因此，诸如TE101模式的寄生模式中的谐振频率向较低频带移动，从而使谐振频率从需要衰减的频带（例如大约二阶更高）引起杂散模式的偏移谐波波段为TEM模式，为工作模式。
