Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wave generator with a built-in distributor that has a distributor and a wave generator in an integrated structure.

In multiple radio line antenna duplexers, there are many cases in which two transmitter/receiver systems are installed as a redundant system: a working unit and a standby unit. In this case, a two-way matching box is connected to the receiver terminal of the duplexer to , have a spare connected to each receiver. In this case, the two-way matching device is connected to the receiving side waver of the duplexer, but conventionally, the waver and the two-way matching device have separate structures, as shown in FIGS. 1a to 1c. That is, in the same figure, 1 is a wave generator, 2 is a two-way matching device, and 3 is a wave generator 1.
This is a mounting bracket for attaching the 2-distribution matching box 2 to the 2-distribution matching box 2. The wave device 1 and the two-way matching device 2 are provided with connection terminals 4 and 5, respectively, and are connected by a cable 8 having connection terminals 6 and 7 at both ends.
As mentioned above, in the conventional system, the two-distribution matching box 2 has a separate structure from the waveform generator 1, so the two-distribution matching box 2
A housing casing, mounting brackets 3, etc. are required to form the housing. In addition, since the connection terminals 4 to 7 and the connection cable 8 are used, it is necessary to adjust the connection cable 8 between the wave device 1 and the two-way matching device 2, and the product cost such as material cost, processing cost, manufacturing cost, etc. becomes higher. The above-mentioned wave transmitter 1 and two-way distribution matching device 2 are often housed within the transmitting/receiving device, but since they are separate structures, they require a lot of storage space, the transmitting/receiving device becomes larger, and there are many connection points, making it difficult to install. bad sex,
This has the disadvantage that the reliability of the circuits of the waveform generator 1 and the two-way matching device 2 is reduced.

The present invention has been made in view of the above points, and
It is an object of the present invention to provide a wave generator with a built-in distributor that can improve workability and reliability of the circuit by making it possible to integrate a wave generator and a distributor.

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 2a to 2c, reference numeral 10 denotes a semi-coaxial bandpass wave device consisting of, for example, four stages of resonators 11a to 11d, and one side of the housing 12 has a mounting plate 13.
The input/output terminals 14 of the wave transmitter 10 are provided through the 2-distribution matching device mounting plate 1 at the bottom of the other side.
Input/output terminals 16 of the two-way matching device are provided through the terminal 5. The input/output terminal 16 is attached to the outer surface of the mounting plate 15 with screws 17, as shown in FIG. The mounting plate 15 is made of, for example, metal or a printed board, and a printed board 19 is fixed to its inner surface with screws 20 via spacers 18 made of metal or plastic. The printed circuit board 19 includes a fourth
As shown in the figure and FIG. 5, for example, a hybrid transformer 21, a ceramic capacitor 22, a resistor 23, etc. constituting the two-distribution matching circuit are attached by soldering. In this case, a hole is formed in the printed circuit board 19 at the mounting portion of the hybrid transformer 21, and the hybrid transformer 21 is inserted into the hole and fixed by, for example, wiring. moreover,
The tip of the center conductor 24 of the input/output terminal 16 is soldered to the printed circuit board 19. The mounting plate 15 on which the two-distribution matching device is mounted is fixed with screws 25 at the lower side of the housing 12, and the two-distribution matching device component is accommodated within the housing 12.

The above-mentioned two-distribution matching device includes a resonator 11 of a wave transmitter 10.
The housing position is set so that it is housed in a place with a low electric field within the housing 12 so as not to affect the elements a to 11d. Thereafter, one end of the coupling loop 26 of the resonator 11a is soldered to the printed circuit board 15, and the other end is connected to the casing 12 by screws 27 or soldering and grounded. That is, the coupling loop 26 of the resonator 11a and the two-distribution matching device are configured to be integrated.

By having the above configuration, there is no need for a 2-distribution matching unit housing case or 2-distribution matching unit mounting bracket, and there is no need for connection terminals or connection cables between the wave transmitter and the 2-distribution matching unit. . This simplifies the structure, eliminates the need for cable adjustment, and reduces product costs such as material costs, processing costs, assembly costs, adjustment costs, and parts costs. In addition, as mentioned above, since no connection cables or connection terminals are used, there are no connection points, which improves the reliability of the entire circuit of the wave transmitter and two-way matching device, allowing for stable operation and reducing adjustment time. can do. Furthermore, by integrating the wave transmitter and the two-way matching device, the overall structure can be made smaller, making it easier to accommodate in the transmitting/receiving device, improving workability, and making it easier to downsize the transmitting/receiving device.

In the above embodiment, a case where a two-way distribution matching device is built into a bandpass waver is shown, but the invention is not limited to this, and it goes without saying that it can be applied to any n-bandwidth waver. The present invention is not limited to pass wave devices, but can be applied to all wave devices such as band-stop wave devices.

As described above, according to the present invention, there is provided a wave generator with a built-in divider that can integrate the wave generator and the distributor into an integrated structure, improve workability, and improve the reliability of the circuit. can do.
