本発明は、UHF帯を含みそれ以上の周波数領域で使用
されるフィルタや発振素子に好適した共振器に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a resonator suitable for filters and oscillation elements used in frequency ranges including and exceeding the UHF band.
従来の ′符 びその5題点

、誘電体共振器やストリップライン等がある。5 Problems with Conventional Resonators used for filters, oscillation elements, etc. in the above frequency range are required to have relatively high sharpness (hereinafter referred to as Q), and as such resonators, Conventionally, there are dielectric resonators, strip lines, etc.

場合に単に並列的に並べただけでは回路を構成せず、別
途コンデンサ等の結合手段が必要であり、構造上複雑化
し、大型化すると共に、組立作業も手間がかかるという
問題点があった。However, the former type of resonator (dielectric coaxial resonator) is relatively expensive, and when used as a filter, simply arranging them in parallel does not constitute a circuit, and requires a separate coupling means such as a capacitor. However, there were problems in that the structure was complicated and large, and the assembly work was time-consuming.

材が多くなり、コスト高は避けられないといった問題点
があった。In addition, the latter type of resonator (strip line) has a thick shape when the operating frequency is low, such as 400 MHz band, and on top of that, since electrodes are formed on the entire back surface of the substrate, there are many electrode members, and the cost is high. There were problems that could not be avoided.

らなる。Figure 1 shows the external configuration of a resonator as an embodiment of the present invention. It consists of a pair of coil patterns 2.3 formed in a shape, and first and second capacitor parts 4.5 connected to the ends of the coil patterns 2, 3.
具体的には、上記コイルパターン2.3は例えば銀ペー

第1及び第2コンデンサ部品4.5は、チップコンデン
サを用いている。Specifically, the coil pattern 2.3 is formed, for example, by screen printing silver paste;
The first and second capacitor parts 4.5 use chip capacitors.
該チップコンデンサ部品4.5はハンダ付により、コイ

る。The chip capacitor component 4.5 is connected to the end of the coil pattern 2.3 by soldering. Each of the coil patterns 2.3 forms a coil in terms of high frequency, so if their inductances are Ll and L2, the resonator has coils LL and LL on both sides of the first capacitor C1, as shown in FIG. A second LC series circuit in which L2 is connected in series
The capacitor C2 is connected in parallel to form an equivalent circuit.
このような等価回路をもった共振器は従来存在せず、従

イルパターン2.3同士が磁気的に結合したり静電容量
をもったりしないように出来るだけ離間させるのが望ま
しい。図示例は最も離間した状態で実施している。A resonator with such an equivalent circuit has not existed in the past, and therefore it can be said that it is a new resonator in terms of the equivalent circuit. The two coil patterns 2 and 3 have appropriate lengths to enable magnetic coupling with other resonators, and are preferably formed as close to the edge of the substrate as possible. Further, it is desirable that the two coil patterns 2.3 in the same resonator are separated as much as possible so as not to be magnetically coupled to each other or have electrostatic capacitance. The illustrated example is implemented in the most distant state.
上記構成の共振器の周波数特性を第3図に示す。この特
性を得るための基板やコイルパターンの賭け法等は次の
通りである。FIG. 3 shows the frequency characteristics of the resonator having the above configuration. The method of selecting the substrate and coil pattern to obtain this characteristic is as follows.
(イ)基板:9X7(m)
厚み 0.8 (1重)
透磁率μ=60
(ロ)コイルパターン二β1=x2=8.0(鶴)W1
=W2= 1.5 (u)
(ハ)コンデンサ: C1−18(pF)C2=43
(pF)
この場合、Qは130と非常に高い値が得られた。(A) Substrate: 9X7 (m) Thickness 0.8 (1 layer) Magnetic permeability μ = 60 (B) Coil pattern 2 β1 = x2 = 8.0 (Tsuru) W1
=W2= 1.5 (u) (c) Capacitor: C1-18 (pF) C2=43
(pF) In this case, a very high value of Q of 130 was obtained.
このような高いQがえられた理由については、推測であ

。The reason why such a high Q was obtained is speculation, but the reason is that the above resonator has a unique circuit configuration that has not been seen before in terms of equivalent circuit, and that the width of the coil pattern 2.3 is widened. This is thought to be due to the lowering of the resistance bone.

に搭載するも自由である。In addition, in the above embodiment, since the substrate is made of ferrite, which is a ferromagnetic material, the inductance of the coil pattern is larger than that when the substrate is made of other materials. The length of the coil pattern needed to obtain this is short, and the resonator can be made smaller accordingly. It should be noted that the present invention is not limited to the above-mentioned embodiments (the design can be changed without departing from the scope of the invention, and although illustration is omitted, a capacitor with leads may be used instead of a chip capacitor on the substrate 1.
You are also free to install it on your computer.

ルタを形成することができるという顕著な効果がある。Also, as explained above, according to the present invention, a resonance circuit having a unique equivalent circuit in which a second capacitor is connected in parallel to an LC series circuit in which coils are connected on both sides of a first capacitor is provided. Since it is a device, it has a high Q suitable for filters, oscillation elements, etc. used at frequencies of 400 MHz or higher, and requires less electrode material than conventional ones, achieving a low cost Bt-6. Also, 1st. Since the second capacitor uses a capacitor component, a ferrite substrate can be used as the substrate, and the resonator can be made smaller. Furthermore, if each coil pattern is formed near the edge of the board,
By connecting a plurality of substrates, magnetic coupling can be easily achieved, which has the remarkable effect of making it possible to form a filter with an extremely simple structure compared to conventional filters.
