Description

一种可调滤波器及可调滤波设备 技术领域
本发明实施例涉及电子通信技术领域，尤其涉及一种可调滤波器及可调滤波设备。
背景技术
可调滤波器是微波通信系统的重要组成部分，广泛的应用于跳频电台、电子对抗、多功能接收机、动态频率分配系统等方面。
目前，存在一种结构简单且便于调节频率的E面可调滤波器。如图1所示，该E面可调滤波器中的矩形波导管在其H平面的中心位置处沿矩形波导管的E平面分割为第一波导部分11和第二波导部分12，且平行于E平面设置的金属板13被第一波导部分11和第二波导部分12夹在中间。此外，在滤波器的矩形波导管中沿金属板13的纵向延伸方向还设置有至少一个电介质板14，至少一个电介质板14被连接到外部驱动机构15。外部驱动机构15可以从外部改变电介质板14和金属板13之间的相对位置关系。也就是说，E面可调滤波器中的电介质板的位置和角度均可以改变。电介质板的位置和角度改变时，H平面方向上的电长度随之改变，从而改变了该E面可调滤波器的中心频率。
但是，由于上述E面滤波器中的金属板的尺寸固定，实际使用过程中，上述E面滤波器的带宽会随着中心频率的增大而变宽，导致该E面滤波器的滤波效果较差。
发明内容
本发明提供一种可调滤波器及可调滤波设备，解决了现有的E面可调滤波器的滤波效果较差的问题。
为达到上述目的，本发明采用如下技术方案：
第一方面，提供一种可调滤波器，该可调滤波器包括腔体、在腔体中设置且第一表面设置有至少一个通孔的滤波元件、驱动机构、与驱动机构连接且贯穿腔体的第一表面的至少一个第一可调元件以 及至少一个第二可调元件。具体的，一个第一可调元件的一端与至少一个通孔中的一个通孔相对设置，一个第一可调元件的一端的横截面面积大于或等于一个第一可调元件的另一端的横截面面积；一个第二可调元件的一端与至少一个通孔中的相邻的两个通孔之间的位置相对设置，一个第二可调元件的一端的横截面面积大于或等于一个第二可调元件的另一端的横截面面积；驱动机构控制至少一个第一可调元件同步移动，以改变至少一个第一可调元件与滤波元件之间的距离，并控制至少一个第二可调元件同步移动，以改变至少一个第二可调元件与滤波元件之间的距离。
由于每个第一可调元件的一端与至少一个通孔中的一个通孔相对设置，至少一个第一可调元件与滤波元件之间距离的变化会使得上述可调滤波器的中心频率随之变化。每个第二可调元件的一端与至少一个通孔中的相邻的两个通孔之间的位置相对设置，至少一个第二可调元件与滤波元件之间距离的变化会使得上述可调滤波器的带宽随之变化。若至少一个第一可调元件与滤波元件之间的距离变大，可调滤波器在中心频率也会增大。在不调节至少一个第二可调元件与滤波元件之间的距离时，可调滤波器的带宽会随着中心频率的增大而变宽，本发明实施例中的可调滤波器可以通过调节至少一个第二可调元件与滤波元件之间的距离来改变该可调滤波器的带宽，从而实现在中心频率增大同时，也保证该可调滤波器的带宽保持不变。
可选的，在本发明实施例的一种可能的实现方式中，上述驱动机构可以包括一个子驱动机构。在这种应用场景中，该子驱动机构与至少一个第一可调元件以及至少一个第二可调元件均连接；该子驱动机构控制至少一个第一可调元件以及至少一个第二可调元件同步移动。
可选的，在本发明实施例的另一种可能的实现方式中，在驱动机构包括一个子驱动机构的应用场景中，该驱动机构中的子驱动机构包括通过紧固件连接的驱动元件和驱动杆，驱动元件包括驱动轴和驱动转子，驱动杆与至少一个第一可调元件以及至少一个第二可 调元件均连接。驱动元件的驱动转子控制驱动元件的驱动轴旋转，以驱动杆移动，至少一个第一可调元件以及至少一个第二可调元件与滤波元件之间的距离。
可选的，在本发明实施例的另一种可能的实现方式中，在驱动机构包括一个子驱动机构的应用场景中，该驱动机构中的子驱动机构还包括位于紧固件与驱动元件的驱动转子之间的固定元件、贯穿固定元件且与驱动杆连接的至少一个抗晃动装置。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行详细地描述。
本发明的说明书和权利要求书及上述附图中的术语“第一”和“第二”等是用于区别不同对象，而不是用于限定特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
另外，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在本发明的描述中，除非另有说明，“多个”的含义是指两个或两个以上。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本发明实施例提供的可调滤波器应用于包括无线接入网设备的 通信系统。
示例性的，无线接入网设备可以为基站。本发明实施例中基站的硬件结构可以参考图2所示的基站的构成部件。如图2所示，基站包括：BBU(英文：Base Band Unit，基带处理单元)、RRU(英文：Radio Remote Unit，射频拉远单元)和天线，BBU和RRU之间可以用光纤连接，RRU再通过同轴电缆及功分器(耦合器)连接至天线，一般一个BBU可以连接多个RRU。
BBU用于完成Uu接口(即终端设备与基站之间的接口)的基带处理功能(编码、复用、调制和扩频等)、RNC(英文：Radio Network Controller，无线网络控制器)和基站之间的逻辑接口的接口功能、信令处理、本地和远程操作维护功能，以及基站的工作状态监控和告警信息上报功能等。
RRU可以包括4个模块：数字中频模块、收发信机模块、功放模块和滤波模块。数字中频模块用于光传输的调制解调、数字上下变频、数模转换等；收发信机模块完成中频信号到射频信号的变换；再经过功放模块放大以及滤波模块滤波后，将射频信号通过天线发射出去。该滤波模块可以是基站中的滤波器。
本发明实施例提供一种可调滤波器，能够在增大可调滤波器的中心频率的同时，通过调节可调滤波器中的至少一个第二可调元件与滤波元件之间的距离来改变该可调滤波器的带宽，使得在增大可调滤波器的中心频率的同时，保持该可调滤波器的带宽不变，从而提高滤波器的滤波效果，避免了可调滤波器的带宽随着可调滤波器的中心频率的增大而变宽。
如图3所示，本发明实施例提供的可调滤波器包括腔体20、在腔体20中设置的滤波元件21、驱动机构22与驱动机构22连接且贯穿腔体20的第一表面(腔体20的第一表面为图3中的xoy面)的至少一个第一可调元件23以及至少一个第二可调元件24。
需要说明的是，为了便于理解，本发明实施例的附图中将腔体20表示成了两部分，实际应用中腔体20为一个整体。
本发明实施例中的滤波元件21可以为金属板。
滤波元件21的第一表面(滤波元件21的第一表面为图3中的xoy面)设置有至少一个通孔210。图4为滤波元件21的俯视图。
实际应用中，由于滤波元件21位于腔体20中，滤波元件21的长度有限，且滤波元件21的第一表面设置有至少一个通孔210，因此，本发明实施例提供的可调滤波器为E面带通滤波器。
可选的，至少一个通孔210可以是均匀设置在滤波元件21的第一表面。
上述至少一个第一可调元件23和至少一个第二可调元件24均位于滤波元件21的一侧(图2中第一可调元件23和第二可调元件24均位于滤波元件21的上方)。
第一可调元件23和第二可调元件24可以为金属元件。
一个第一可调元件23的一端与至少一个通孔中的一个通孔210相对设置。第一可调元件23的一端的横截面面积大于或等于该第一可调元件23的另一端的横截面面积。
具体的，第一可调元件23可以为圆柱形，也可以为由第一圆柱和第二圆柱组成的元件，且第一圆柱的底面面积小于第二圆柱的底面面积(图3中示出了这种形状的第一可调元件23)。
一个第二可调元件24的一端与至少一个通孔中的相邻的两个通孔210之间的位置相对设置。第二可调元件24的一端的横截面面积大于或等于该第二可调元件的另一端的横截面面积。
第二可调元件24的构造、形状均可参考上述对第一可调元件23的描述，此处不再进行详细赘述。
需要说明的是，本发明实施例中的第一可调元件23的体积与第二可调元件24的体积可以相同，也可以不同，本发明实施例对此不作具体限定。
本发明实施例中的每个第一可调元件23和每个第二可调元件24在安装过程中均可独立调试，这样可以降低加工、装配过程中造成的误差，从而降低可调滤波器的误差。
驱动机构22与至少一个第一可调元件23和至少一个第二可调元件24均连接。
驱动机构22控制至少一个第一可调元件23沿垂直于腔体20的第一表面的方向同步移动，进而改变至少一个第一可调元件23与滤波元件21之间的距离。
具体的，在驱动机构22的作用下，至少一个第一可调元件23与滤波元件21之间的距离可以变大，也可以减小。至少一个第一可调元件23与滤波元件21之间的距离与该可调滤波器的中心频率成正相关关系。至少一个第一可调元件23与滤波元件21之间的距离变大时，该可调滤波器的中心频率变大。相应的，至少一个第一可调元件23与滤波元件21之间的距离变小时，该可调滤波器的中心频率变小。
此外，该可调滤波器的驱动机构还控制至少一个第二可调元件24沿垂直于腔体20的第一表面的方向同步移动，以改变至少一个第二可调元件24与滤波元件21之间的距离。
由于第二可调元件24的一端与至少一个通孔中的相邻的两个通孔210之间的位置相对设置，因此，可调滤波器的带宽会随着至少一个第二可调元件24与滤波元件21之间的距离的变化发生改变。因此，本发明实施例提供的可调滤波器可以在该可调滤波器的中心频率增大时，通过调节至少一个第二可调元件24与滤波元件21之间的距离，避免该可调滤波器的带宽变宽，这样，本发明实施例提供的可调滤波器的带宽可以保持不变。
结合图3，如图5所示，本发明实施例提供的可调滤波器中的驱动机构22包括一个子驱动机构22a。该子驱动机构22a包括通过紧固件220连接的驱动元件221和驱动杆222。其中，驱动元件221包括驱动轴221a和驱动转子221b，驱动杆222与至少一个第一可调元件23以及至少一个第二可调元件24均连接。
驱动元件221可以为电动机。
驱动元件221的驱动转子221b控制驱动元件221的驱动轴221a旋转，使得驱动杆222移动，以改变至少一个第一可调元件23以及至少一个第二可调元件24与滤波元件21之间的距离。
可选的，本发明实施例中的第一紧固元件220可以为螺母，也 可以为卡扣，还可以为其他用于起固定作用的元件，本发明实施例对此不作具体限定。
图5中用螺母表示第一紧固元件220。若第一紧固元件220为螺母，相应的，第一驱动元件221的驱动轴221a上有螺纹。
进一步地，结合图5，如图6所示，本发明实施例提供的可调滤波器中的子驱动机构22a还包括位于紧固件220与驱动元件221的驱动转子221b之间的固定元件223、贯穿固定元件223且与驱动杆222连接的至少一个抗晃动装置224。
抗晃动装置224可以由导杆和导套组成。抗晃动装置224用于提高第一驱动杆222在移动或者静止过程中稳定性。
进一步地，结合图6，如图7所示，本发明实施例提供的可调滤波器中的子驱动机构22a还包括与固定元件223以及驱动杆222均连接的至少一个伸缩装置225。
伸缩装置225可以是由至少一组弹簧组成的装置。图7中，每个伸缩装置225均用弹簧表示。
在至少一个伸缩装置225的作用下，能够提高驱动杆222在移动过程中的稳定性，同时提高可调滤波器的抗振能力。
进一步地，结合图7，如图8所示，本发明实施例提供的可调滤波器还包括与驱动杆222连接、设置在第一腔体20的第一表面的两端且贯穿腔体20的第一表面的至少两个第三可调元件25。
驱动杆222的移动控制至少两个第三可调元件25同步移动，以改变至少两个第三可调元件25与滤波元件21之间的距离。
第三可调元件25的构造、形状均可参考上述对第一可调元件23的描述，此处不再进行详细赘述。
随着至少一个第三可调元件25与滤波元件21之间的距离的变化，可调滤波器的中心频率的调节范围发生变化。
为了更加方便理解，结合图8，图9是从图8中xoz平面所在的方向观察时的剖视图。
结合图8，图10是图8示出的可调滤波器的俯视图。
可选的，若本发明实施例提供的可调滤波器包括至少一个第一 可调元件23以及至少一个第二可调元件24，则可调滤波器的驱动机构也可以包括两个子驱动机构。两个子驱动机构中的一个子驱动机构与至少一个第一可调元件23连接，另一个子驱动机构与至少一个第二可调元件24连接。一个子驱动机构控制至少一个第一可调元件23同步移动；另一个子驱动机构控制至少一个第二可调元件24同步移动。
具体的，该场景中的两个子驱动机构中的每个子驱动机构的结构均相同，可以参考上述图5-图8中任一附图所示的子驱动机构的结构。
可选的，若本发明实施例提供的可调滤波器包括至少一个第一可调元件23、至少一个第二可调元件24以及至少一个第三可调元件25，则可调滤波器的驱动机构也可以包括两个子驱动机构。两个子驱动机构中的一个子驱动机构与至少一个第一可调元件23连接，另一个子驱动机构与至少一个第二可调元件24以及至少一个第三可调元件25均连接；或者，两个子驱动机构中的一个子驱动机构与至少一个第一可调元件23以及至少一个第三可调元件25均连接，另一个子驱动机构与至少一个第二可调元件24连接；或者，两个子驱动机构中的一个子驱动机构与至少一个第一可调元件23以及至少一个第二可调元件24均连接，另一个子驱动机构与至少一个第三可调元件25连接。除了上述连接方式以外，还可以为其他连接方式，此处不再进行一一列举。
可选的，若本发明实施例提供的可调滤波器包括至少一个第一可调元件23、至少一个第二可调元件24以及至少一个第三可调元件25，则可调滤波器的驱动机构也可以包括三个子驱动机构。三个子驱动机构分别连接一种类型的可调元件。这里，第一可调元件23为一种可调元件，第二可调元件24为一种可调元件，第三可调元件25为另一种可调元件。
图11示出了属于该场景的可调滤波器的俯视图。图11中22a、22、22c分别表示不同的子驱动机构。
本发明实施例还提供一种可调滤波设备，该可调滤波器设备包 括如上述图2-图11中任一附图所示的可调滤波器。
