Abstract

The utility model discloses a multiplexer common-cavity coupling combiner. A common cavity is arranged between a first filter and a second filter of the combiner; a common resonance rod is arranged in the common cavity; and the common resonance rod is connected with a connector through a jumper wire. For the combiner, taps adopt a common cavity coupling mode, so that the problem of the coupling crosstalk of the multiplexer multiple taps is solved, the crosstalk of more than three taps of the combiner can be reduced to the minimum, and the problems that when being coupled in a conventional method, the multiplexer taps influence each other and are not easy to control are solved, therefore, the combiner is beneficial to improving production efficiency, sufficiently utilizing space, and reasonably reducing cost.

Description

Multiplexer is chamber coupling mixer altogether

Technical field

The utility model relates to a kind of multiplexer chamber coupling mixer altogether.

Background technology

The cavity mixer as important microwave device in the microwave regime extensive use, owing to provided 3G license in recent years, particularly the adding of TD frequency range causes the mobile communication industry to derive multiple three and closes the above product in road, take original tap connected mode like this, not only be difficult to technically realize, and also suitable big of debugging difficulty.

3G license, TDA, the TDF particularly adding of TDE frequency range 2300-2380MHz causes the mobile communication industry to derive multiple multiplexer more than 3 tunnel, tap coupling is crosstalked, and more wayward (one adopts conventional method design 3 the tunnel or more, see Fig. 2, tap is crosstalked quite serious), existing mixer among Fig. 2, has filter 1, filter 2 102 and filter 3 103, first resonant cavity of each filter is connected with connector 105 by tap wire jumper 104 separately, because wire jumper has several to cause debugging efficiency low, the row chamber is difficulty relatively, and cavity space can not rational Application increase cost.

Summary of the invention

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of multiplexer chamber coupling mixer altogether, adopts the mode of chamber coupling altogether, is beneficial to the division and the combination of microwave regime frequency band, realizes the simplification of multiplexer mixer.

The utility model technical solution problem adopts following technical scheme:

Multiplexer is chamber coupling mixer altogether, between first filter of described mixer and second filter shared chamber is set, and is provided with the common resonant rod in the described shared chamber, and described common resonant rod passes through a wire jumper and is connected with connector.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

Mixer of the present utility model, chamber coupled modes are altogether adopted in tap, solve the multiplexer multichannel tap coupling difficult problem of crosstalking, the tap of multiplexer more than three tunnel can be crosstalked and be reduced to minimum, solved multiplexer conventional method tap coupling and interacted, a uppity difficult problem helps enhancing productivity, make full use of the space, rationalization reduces cost.

Advantage of the present utility model, effect are:

1, reduces the experiment difficulty, shorten the R﹠D cycle;

2, be beneficial to rationalization and utilize the space, reduce cost;

3, reduce the production difficulty, enhance productivity;

4, highly versatile is applicable to the combination in any of microwave regime frequency band, realizes the simplification of multiplexer.

Description of drawings

Fig. 1 is the structural representation of the utility model mixer; Fig. 2 is the structural representation of existing mixer.

Number in the figure: 101 filters, one, 102 filter, two, 103 filters, three, 104 tap wire jumpers, 105 connectors, 201 first filters, 202 second filters, 203 shared chambeies, 204 resonance rods.

Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

Embodiment

Embodiment: in conjunction with Fig. 2, the multiplexer of present embodiment is chamber coupling mixer altogether, between first filter 201 of mixer and second filter 202, shared chamber 203 is set, be provided with common resonant rod 204 in the described shared chamber 203, described common resonant rod is connected with connector 105 by a tap wire jumper.

The utility model adopts the mode of common cavity coupling, the shared common cavity tap and adjustable of 2-4 path filter can be determined that by emulation the power of coupling can be eliminated the problem that the multiplexer tap is crosstalked substantially; A difficult problem of avoiding the multiplexer tap to crosstalk from design can reduce the construction cycle, and enhances productivity, and also is beneficial to and rationally utilizes the space to reduce cost when product design.

Claims

1. multiplexer is total to chamber coupling mixer, it is characterized in that between first filter (201) of described mixer and second filter (202), shared chamber (203) being set, be provided with common resonant rod (204) in the described shared chamber (203), described common resonant rod is connected with connector (105) by a wire jumper.
