Therefore, it is necessary to open the cover of the filter, and then change the contact shape or welding position. It also takes a long time to adjust and causes high cost. Because the input terminal (connector) 71 is connected to a grounded resonant rod, a DC cut device is required when a DC voltage is applied to the input terminal.

When DC voltage is applied to the input terminals, DC bias is required. In addition, in the antenna system shown in FIG. 3A and FIG. 3B, since the antenna 93 connected to the input terminal 91 is not grounded, a direct current is added to the input terminal.

Description of the invention (9) The amount of insertion of the adjusting screw 17 inside the vibrator 14 can increase or decrease the electromagnetic_combination (the strength of the electromagnetic coupling). Since the coupling antenna 13 of the first embodiment is not in contact with the outer wall (frame) of the resonance rod 15 and the filter device 10, even if a DC (direct current) voltage is applied to the input terminal, there is no need to separately provide direct current. Biasing has the advantages of the antenna light-coupling system. In the first embodiment described above, an example has been described in which a U-shaped or j-shaped antenna is implemented by a slender rod conductor made of a metal material. However, other embodiments may be used, such as a plate-shaped insulating substrate. The conductor pattern is used to form the same antenna shape. In FIGS. 7A to 7C, the state of the coupled antenna of the present invention is explained. In the first embodiment, the antenna is provided with a base plate 38 and a straight line from the floating terminal. An example of a substrate consisting of a conductor pattern on the side of the conductor-to-lead end 39 to the side including a line conductor, a pattern connected to the conductor pattern 33 on the filter 3, and a 3-phase frequency signal via body pattern 33. Antenna substrate) 3 8 is formed of an insulating substrate, and an end portion (pattern) 3 9 for supplying a high-frequency signal is formed on the surface. The other end portion (floating end) 4 which is an open end is resonant with the resonator. The rods 3 and 5 are arranged adjacent to each other in parallel, forming a ϋ-shaped or J-shaped conductor pattern (antenna) 33. The antenna device (antenna) 33 is included on a plane perpendicular to the long side of the device. The antenna substrate 38 is inserted through the through hole from the substrate surface on the opposite side, and is inserted into the input conductor rod 32, and the tip of the conductor rod 32 is connected by soldering or the like. Directly supplied by the wheel-in terminal (connector) 31 and the conductor rod 32, and the conductor pattern 33 and the resonance rod 35 of the antenna substrate 38 are provided by 554568.

The antenna substrate 38 is in contact with the outer wall (frame) of the amplifier device 30, which is the same as = rod 35 = filtering, even if DC power is added to the wheel-in terminal 31: not only the bismuth-shaped phase bias device. It is not necessary to provide DC removal. In FIG. 7C, the arrangement of the conductors on the antenna substrate between the screws is described. The case of the 3rd _ Xiyi 3, ,, vibrator, and tone of the tune 夭 Jun Fu 柘 甘 gan ^ In other words, from the resonance rod 35 side, the relationship between the other components will be explained. In this example *, · the conductor pattern of the a antenna is a j-shaped conductor

Side 钿 邛 39, the front end of conductor rod 32 is connected by welding or other methods. The linear conductor including the other side 钿 4 (floating 鳊) 4 〇 is adjacent to the resonance rod 35 to be arranged in parallel. This straight conductor part is responsible for the coupling rod with the initial stage. Electromagnetic coupling. An adjustment screw 3 7 is provided above the linear conductor including the end portion 39. By adjusting this, the position of the entire screw 37 (insertion of the adjustment screw 17 inside the resonator 14) can increase or decrease the amount of electromagnetic coupling (electromagnetic coupling).

Description of the invention (π)-the distance between the resonator and the resonator 15 and (3) adjusting the position of the adjusting screw 17 near the coupling antenna 3. / Connector '^ The following describes the coupling operation, coupling characteristics, and adjustment of the south frequency signal in the coupling system of the filter device in the first or second embodiment. The U-shaped or J-shaped coupling antenna 13 (or 33) of the first conductor portion 1, 3a (or 33a) and the input terminal u (or 31) and the center conductor of the conductor rod 12 (or 32) are welded, etc. Connected, and the electromagnetic energy supplied from the input terminal n (or 31) flows through the first conductor portion 138 (or 33 &) of the U-shaped or j-shaped coupling antenna to the second conductor portion 131) (or 331)) . Because the second conductor part 13b (or 33b) of the coupling antenna 13 (or 33) is adjacent to the resonance rod 15 (or 35) and is arranged in parallel, it is mainly in this part that is connected to the initial resonance rod 5 (or 3 5 ) Use electromagnetic coupling to excite the primary resonator. The coupling strength of the excitation at the second conductor portion 13b (or 33b) of the coupling antenna 13 (or 33), as shown in Figs. 6A to 6C, can change the parallelism with the resonance rod 15 (or 35) Or the length of the adjacent interval, or the length of the first conductor portion 13a (or 33a), and so on. In addition, the adjustment of the electromagnetic coupling i of the excitation can adjust the adjusting screw 1 7 (closed to the first conductor portion 1 3 a (or 3 3 a) of the antenna connected to the input terminal 11 (or 31)) Or 37). When adjusting the amount of electromagnetic coupling with the adjustment screw 17 (or 37), insert the entire screw 1 7 (or 3 7) to make the first conductor part 1 3 a (or 3 3 a) of the antenna and The longer the overlapping portion of the adjustment screw is, the weaker the electromagnetic coupling amount is. This is because the adjustment screw 17 (or 37) will affect the first conductor section passing through the antenna

Page 17 554568 V. Description of the invention (12) The electromagnetic energy of 13a (or 33a) is used to control the electromagnetic energy reaching the second conductor part 13b (or 33b) participating in the coupling. Because the adjusting screw 7 (or 37) has a large suppression amount, by setting the coupling antenna 1 3 (or 3 3) adjacent to the initial resonance rod 1 5 (or 3 5), the amount of electromagnetic coupling can be increased. Variable range. Fig. 8 is a diagram illustrating the difference between the characteristics of the wave filter between the first or second embodiment of the present invention and a conventional example. The horizontal axis is the insertion amount of the adjustment screw, and the vertical axis is Qext (external Q), which indicates the amount of electromagnetic coupling. Here, the larger the value of Qext, the weaker the electromagnetic coupling, and the smaller the Qext, the stronger the electromagnetic coupling. As shown in FIG. 8, in the conventional example, as the insertion amount of the adjustment screw of the coupling antenna is increased, the value of Qext will decrease, and the change amount of Qext is smaller when the insertion amount of the adjustment screw is smaller. When the amount of insertion becomes large, the filter characteristic in which the amount of change becomes large. In contrast, in the u-shaped or] -shaped coupled antennas of the present invention, == the insertion amount of the adjusting screw inserted in parallel with the coupling antenna, and the value of the adjusting screw tends to increase. When the amount of insertion is large, the amount of change in Qext is large. When the area of small amount of insertion is small, the characteristics of the twirled wave and the wave filter are changed. In particular, the value of Qext is 3 times or more (the variable amplitude of the electromagnetic coupling amount is also 3 =, Erzhi: Subscript, the variable amplitude of the entire Qext value can be 10 times the same as the antenna shape. When adding the word / or; font-shaped or j-shaped coupling antenna, the change of Qext will change when the amount of U insertion decreases, and it will consume helical and silk in the weak coupling area. The filter characteristics have the opposite relationship. The support is large. That is, the method of adjusting the filter characteristics with the insertion of the adjustment screw of Xi Xiu 554568

First, the electromagnetic coupling of the high-frequency signal supplied to the first-stage resonator is gradually strengthened until it becomes the best electrical weakness in the filter characteristics. ^ Coupling, therefore, 'as in the previous example, the end point of the adjustment is smaller, the area) is greater than the start point of the adjustment (the area where the Qext is large), and the Qext is greater than the start point of the adjustment. However, the Qext of the adjusted end point is small to make it easy to adjust. As can be understood from FIG. 8 / compared with the filter characteristics of the known example of s1, it is easier to adjust the filter device of the U-shaped or j-shaped filter to fit the antenna in the present invention. In the example shown in Fig. 8, the Qext of the filter device is designed to be about 20 as desired. The variable range of Qext in the conventional example is about 10, and the maximum is about Qext = 34. Compared with this, when the u-shaped or J-shaped coupled antenna in the present invention, the variable range of Qext can be about 15 ~ 80, the maximum can be Qext = 80 or more, it is possible to make Qext reach the conventional example. 2 times more. According to the above filter characteristics of the U-shaped or J-shaped coupled antenna of the present invention, the adjustment screw is first inserted into the depth, and then the insertion amount is reduced. The electromagnetic coupling amount is changed from about Qext = 80, which can be changed all the way to electromagnetic coupling. The goal of smaller changes in the amount is (^ == 20 fine adjustment). For example, the duplex (D u ρ 1 e X) system has been applied to the filter device in the early stage of the invention. It has been explained that: Λwai 'can also be applied to other triplex devices equipped with an oscillating wave device. The following description uses a duplex device as an example to explain the third embodiment. The duplex device is shown in FIG. 9A. Block diagram

Adjustment screw for front position. In the third embodiment, the same method of adjusting the coupling amount as in the first or second embodiment described above can be used. In particular, when it is adjusted with an adjustment screw, it is easy to adjust because it is not necessary to open the upper cover. In addition, when an antenna conductor is formed on a substrate, a specific pattern is formed in advance, so that its production accuracy is high, and its reproducibility is also high compared with a method such as tap coupling. According to another embodiment of the present invention, a metal wire may be used in place of the U-shaped or J-shaped conductor rod or the conductor pattern on the substrate in the first to third embodiments. By using a metal wire, the u-shaped or J-shaped shape can be easily adjusted. As the insulating substrate ′ in the second and third embodiments, a plate-shaped insulator such as a thin-film plate, a foamed styrene (sty r 〇 1) plate, or a plastic plate can be used. In addition, as the conductor pattern of the antenna substrate, a shape obtained by deforming a U-shape or a J-shape can be used. Industrial use possibilities ...
