る必要があり、多くの時間と労力を要する。Fig. 1 is a sectional view of the main part (BB sectional view in Fig. 2) showing an example of a conventional duplexer, and Fig. 2 is a sectional view taken along AA in Fig. 1.
1 is a common housing made of a conductor, B and 2 are resonant elements, 3
1 and 3a are interstage coupling lit adjustment elements, 4° and 4 are resonant frequency fine adjustment elements, which are composed of an electrode plate and a gap adjustment screw between the electrode plate 0 and the open end of the resonant element. 5 is a common input/output coupling element, and 6 is a common input/output terminal. In this duplexer, the axial length of the resonant element 21 is determined to be approximately the length of the resonant wavelength cavity, and interdigital band-pass filters (hereinafter referred to as band-pass filters) with a center frequency f are arranged with opposite polarities to each other. The filter is abbreviated as BPF), and the axial length of the resonant element 2a is selected to be approximately the length of the resonant wavelength input a, and they are arranged with opposite polarities to form an ink digital type BPF with a center frequency f-. Therefore, the gaps between the open ends of each of the 8-oscillation elements 2. and 2a and the housing wall are arranged alternately in the vertical direction of the housing. The outer ends of the four gap adjustment screws also protrude alternately from the earthen wall and bottom part of the casing I, making the overall shape complex and large.In addition, the groin joint adjustment elements 3t & 3. Since it is formed by the conductor tit inserted from the side wall of the body 1, milling is required to make the insertion slit, which increases the number of machining steps and increases the cost. Furthermore, since there is a large error between the theoretical value and the experimental value during design and manufacturing, it is necessary to experimentally confirm the dimensions of each component, arrangement spacing, etc. and correct any errors, which requires a lot of time and effort. It takes.

には、誘電体の誘電率に応じて設問結合係数が変化する
ため設計が極めて困難である。If a combline type BPF is used as the BPF', the gap between the open end of the resonant element and the housing and the outer end of the screw of the resonant frequency fine adjustment element are arranged on the same side, making the whole structure simpler. Although it is small, in the conventional combline type BPF, the axial length of the resonant element is formed to be approximately equal to the resonant wavelength I, and a load capacity is added between the electrode plate attached to the open end of each resonant element and the housing wall. By doing so, resonance is achieved and the crotches are coupled through a coupling capacitance.Since the load capacitance requires a relatively large value, an electrode plate attached to the open end of the resonant element and one housing are used. The gap between the walls is narrow, the voltage resistance is poor, and the load capacity changes significantly as the gap changes due to changes in ambient temperature, making it difficult to obtain stable electrical characteristics. Since the structure is configured to perform interstage coupling, if a dielectric is interposed between the resonant element and the housing to reduce the overall size, the coupling coefficient will change depending on the dielectric constant of the dielectric. Extremely difficult to design.

The purpose of the present invention is to realize a duplexer for very short waves or microwaves that is hardly affected by the dielectric constant and is easy to design and manufacture.
