Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the high power filter in the present embodiment includes at least one common port 110 and a plurality of common ports 120, where the common port 110 is an input port or an output port for combining multiple signals, and the common ports 120 are input ports or output ports for not combining signals. Taking the common port 120 as an input port and the common port 110 as an output port, the signals input from the common ports 120 are combined into one signal at the common port 110 for output.

Wherein the high power filter further comprises a cavity 130, the common port 110 is connected to a first inner conductor 140 located on a side wall of the cavity 130, and the common port 120 is connected to a second inner conductor 150 located on a side wall of the cavity 130. Wherein a direct current is conducted between the first inner conductor 140 and the second inner conductor 150.

The following is a description of the high temperature resistant components in the high power filter. This high temperature resistant subassembly includes: a first inner conductor 140, a first coupling rod 160, a first spacer 170, and a first screw 180.

Wherein the first inner conductor 140 is located on the sidewall of the cavity 130 of the high power filter, and the first inner conductor 140 is connected to the common port 110 of the high power filter. The first inner conductor 140 is also opposite to the first coupling rod 160, and the first coupling rod 160 is connected with the first resonance rod 190 inside the cavity 130. Wherein the first resonant bar 190 may be the resonant bar closest to the common port 110.

The first screw 180 is fixed with the first coupling rod 160 through the first spacer 170 so that the first inner conductor 140 is insulated from the cavity 130. Wherein, the first washer 170 and the first screw 180 are made of high temperature resistant material. Because the first gasket 170 and the first screw 180 are made of high temperature resistant materials, the first gasket 170 is not melted even if the temperature of the common port 110 is high, so that the electrical performance of the high-power filter can be ensured to be effective, and the reliability of the high-power filter is improved.

In one implementation, the refractory material may be a PPS (polyphenylene sulfide) material. Of course, the refractory material may be other materials, and the refractory material is not limited in this embodiment.

In this embodiment, the first inner conductor 140 is opposite to at least two first coupling bars 160, and each first coupling bar 160 is fixed with a first screw 180 passing through the first spacer 170. Further, each first coupling rod 150 corresponds to at least one second inner conductor 150.

As shown in fig. 1, the first inner conductor 140 is opposite to two first coupling bars 160, wherein one first coupling bar 160 is located in one signal path, i.e., corresponds to one second inner conductor 150, i.e., corresponds to the uppermost one of the normal ports 120 on the left side in fig. 1; the other first coupling bar 160 is located in three signal paths, i.e. corresponding to three second inner conductors 150, i.e. corresponding to three common ports 120 at the lower left side in fig. 1.

In this embodiment, the second inner conductor 150 is opposite to a second coupling rod, which is connected to a second resonance rod in the cavity 130, and the second coupling rod is fixed to a second screw passing through a second gasket. The second coupling rod may be the same as the first coupling rod 160, and in this embodiment, for the sake of distinction, the coupling rod at the common port 110 is referred to as the first coupling rod 160, and the coupling rod at the common port 120 is referred to as the second coupling rod. Similarly, the second resonant rod may be the same as the first resonant rod 190, and in this embodiment, for the sake of distinction, the resonant rod at the common port 110 is referred to as the first resonant rod 190, and the resonant rod at the common port 120 is referred to as the second resonant rod. The second gasket may be the same as the first gasket 170, and in this embodiment, for the sake of distinction, the gasket at the common port 110 is referred to as the first gasket 170, and the gasket at the common port 120 is referred to as the second gasket. The second screw may be identical to the first screw 180, and for the sake of distinction in this embodiment, the screw at the common port 110 is referred to as the first screw 180, and the screw at the common port 120 is referred to as the second screw. The second coupling rod, the second resonance rod, the second spacer and the second screw are not shown in fig. 1.

Since the temperature at the general port 120 is not high, the second gasket and the second screw may be both made of general materials. Alternatively, in order to further improve the reliability of the high power filter, the second gasket and the second screw may be made of high temperature resistant materials.

In summary, in the high temperature resistant assembly provided by this embodiment, the first inner conductor in the high temperature resistant assembly is located on the sidewall of the cavity of the high power filter, the first inner conductor is opposite to the first coupling rod, the first coupling rod is connected to the first resonance rod in the cavity, and the first screw passes through the first gasket and is fixed to the first coupling rod.

The embodiment also provides a high power filter with a high temperature resistant component, which comprises the high temperature resistant component shown in fig. 1. For ease of understanding, referring to fig. 2, fig. 2 shows a schematic diagram of the cavity of the high power filter.

The high power filter in this embodiment may further include a cover plate (not shown in fig. 2) that is used with the cavity to encapsulate the high temperature resistant component. Namely, the cover plate and the cavity can form a closed space, and the high-temperature resistant assembly is positioned in the closed space.

In an alternative embodiment, the top of the cover plate is provided with a plurality of openings (not shown in fig. 2), and each opening is provided with an adjusting screw (not shown in fig. 2) for adjusting the height of the resonant rod. Wherein, adjust the height of resonance pole promptly and adjust the screw and go deep into the degree of depth of resonance pole to adjust the frequency of high-power filter.

The above description should not be taken as limiting the embodiments of the invention, and any modifications, equivalents, improvements and the like which are within the spirit and principle of the embodiments of the invention should be included in the scope of the embodiments of the invention.
