Communication equipment and filter thereof

The invention discloses communication equipment and a filter thereof. The filter comprises: a shell having a first direction and a second direction perpendicular to each other; and a filtering branch which is arranged on the shell, consists of ten filtering cavities which are sequentially coupled, and forms three cross coupling zero points. The distance between the center of the nth filtering cavity of the filtering branch and the center of the (n + 1) th filtering cavity of the filtering branch is a preset fixed value, and n is an integer greater than or equal to 1 and less than or equal to 9. By means of the mode, the filtering cavities of the filtering branches are arranged at equal intervals, the consistency of the filter can be improved, and layout and debugging are facilitated. 本申请公开了一种通信设备及其滤波器。该滤波器包括：壳体，具有相互垂直的第一方向和第二方向；滤波支路，设置在壳体上，由依次耦合的十个滤波腔组成，并且形成三个交叉耦合零点，滤波支路的第n滤波腔的中心和第n+1滤波腔的中心之间的距离为预设的固定值，n为大于等于1且小于等于9的整数。通过上述方式，滤波支路的滤波腔等间距间隔设置，能够提高滤波器的一致性，且便于布局和调试。
