AI Technical Summary

Problems solved by technology

RF broadband ferrite materials are the basis of RF broadband ferrite devices. This type of device realizes tasks such as impedance exchange in the RF segment, power distribution and synthesis, and power transmission. The first generation of soft magnetic materials for existing RF broadband ferrite materials R100 and R1K are suitable for use in the 40-450MHz frequency band, and the second-generation R1K5 and R1K8 of radio frequency broadband soft ferrite materials are suitable for use in the 40MHz-550MHz and 40MHz-750MHz frequency bands, which cannot meet the needs of technological development.

Abstract

A high-conductivity Ni-Zn ferrite is prepared from iron oxide, neckelous oxide, zinc oxide, copper oxide, and manganese carbonate through proportional mixing, precalcining, sand grinding, granulating, shaping and sintering. Its advantages are high magnetic conductivity up to R3K, broad spectrum, high gain and reflection loss, and low insertion loss.

Description

technical field [0001] The invention relates to an inorganic material magnet, in particular to a nickel-zinc high-conductivity ferrite and a preparation method thereof. Background technique [0002] With the development of technologies such as CATV network, computer network, communication network, broadcasting network, anti-electromagnetic interference, and electromagnetic compatibility, the independent network system has developed into a broadband comprehensive information network, which requires RF broadband ferrite devices in the system, especially power splitters. The working frequency band of splitters and distributors is widened, which is suitable for multi-functional, digital, miniaturized, high-sensitivity application technical requirements and absorbing radio waves, preventing radio wave leakage, etc., namely: broadband, low insertion loss, high gain, high mutual Isolation and high reflection loss are taken as the overall technology of the system, and the key basic ...
