Abstract

The invention provides a magnesium alloy as well as a preparation method thereof and a cavity filter. The magnesium alloy comprises the following components in percentage by weight: 1.5-3.5% of samarium, 0.2%-1.0% of zirconium, 0.01%-0.1% of silver and the balance magnesium. According to the magnesium alloy provided by the invention, a little samarium, zirconium and sliver is added into magnesium, so that casting performances of the magnesium alloy are improved; mechanical strength, heat conduction and the like of magnesium alloy are strengthened; the preparation method for the magnesium alloy is simple; a cavity and a cover body of the cavity filter are made of the magnesium alloy, so that the cavity filter has the advantages of light weight, good mechanical property and good heat radiation, and therefore, production cost of the filter is greatly reduced; and the magnesium alloy is easy to assemble and manufacture.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to a magnesium alloy, a preparation method thereof, and a cavity filter. Background technique [0002] In a base station system for mobile communications, a communication signal carrying communication data within a specific frequency range is usually transmitted through a transmitting antenna, and the communication signal is received through a receiving antenna. The signal received by the receiving antenna includes not only communication signals carrying communication data within the above-mentioned specific frequency range, but also many clutter or interference signals outside the above-mentioned specific frequency range. In order to obtain a communication signal carrying communication data within a specific frequency range transmitted by the transmitting antenna from the signal received by the receiving antenna, it is usually necessary to filter the signal received...
