Description

Satellite antenna equipment, transceiver module and filtering unit thereof

technical field

The invention relates to a satellite antenna device, a transceiver module and a filtering unit thereof.

Background technique

With the development of space technology, satellite transmission technology has gradually entered the daily life of ordinary people. For example, the Global Positioning System (Global Positioning System, GPS) used for navigation, or the Satellite News Gathering (SNG) system used by TV stations 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.

Please refer to FIG. 1 , which 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 12 are connected to the upper and lower sides of the filter base 11 . The filter base 11 has a filter space 111 and a plurality of filter grooves 112 arranged at intervals. By moving the position of the adjustment component 12, the depth of the filter grooves 112 can be adjusted to correspond to different filter ranges.

Therefore, when the Ka or Ku band transmission signal enters the filter 1 , the wavelength corresponding to the distance between the filter slots 112 can directly pass through the filter space 111 . However, other wavelengths will fall into the filter slot 112, resonate and cancel.

However, since the depth of the filtering groove 112 is adjustable, when adjusting corresponding to different filtering 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 demoulded, the surface of the filter groove 112 is often not smooth enough, thereby affecting the filtering effect.

Therefore, how to design a filter with good filtering effect, which can be applied to satellite antenna equipment and transceiver modules, has become one of the important issues.
