AI Technical Summary

Problems solved by technology

However, other wavelengths will fall into the filter slot 112, resonate and cancel
[0005] However, since the depth of the filter groove 112 is adjustable, when adjusting corresponding to different filter ranges, the filtering effect of the filter 1 may be poor due to human adjustment errors or mechanical errors caused by materials or manufacturing processes.
In addition, the position of the adjustment assembly 12 may be continuously moved, resulting in loss of the adjustment assembly 12 and damage to the filter 1.
In addition, the existing filter 1 is mostly made of aluminum-zinc alloy with a relatively high proportion of aluminum. During the manufacturing process, after the filter 1 is demolded, the surface of the filter groove 112 is often not smooth enough, thereby affecting the filtering effect.

Abstract

The invention relates to a filter unit comprising a filter base and a cover body. The filter base is provided with a plurality of first filter slots arranged at intervals; the cover body and the filter base are jointed to form a filter space, and the filter base is provided with a plurality of second filter slots which are arranged at intervals and correspond to the first filter slots, wherein the materials of the filter base and the cover body contain zinc-aluminium alloy. The invention also discloses satellite antenna equipment using the filter unit and a transceiver module thereof.

Description

technical field [0001] The invention relates to a satellite antenna device, a transceiver module and a filtering unit thereof. Background technique [0002] With the development of space technology, satellite transmission technology has gradually entered the daily life of ordinary people. For example, a Global Positioning System (Global Positioning System, GPS) used for navigation, or a Satellite News Gathering (SNG) system used by a TV station for live broadcasting. Among them, for example, in the SNG system, satellite antenna equipment is used to transmit and receive signals, and in order to make the signals transmitted and received by satellite antenna equipment clear, filters are often used to filter out interference signals. [0003] Please refer to figure 1 As shown, it is a cross-sectional view of a filter 1 of a conventional satellite antenna device. The filter 1 includes a filter base 11 and a plurality of adjustment components 12 , and the adjustment components ...
