R80p Rf Broadband Power Nizn Iron Oxide Material

In this paper, the application and preview of wide band RF high power ferrite materials are described. The mechanism of power loss of wide band RF high power ferrite materials is analyzed. Accordingly, the methods to decrease power loss of NiZn ferrite material is proposed. The relationship between the composition and processing factors and the properties of conveying high power RF signal are investigated. The methods to estimate the properties of RF wide band high power NiZn ferrite materials in high frequency high power application by Q factor measured at high frequency low magnetic field are discussed. A high power wide band NiZn ferrite material typed R80P can be applied for high power wide band ferrite component is developed .The measurement data of R80P wide band high power ferrite NiZn material is as follow.The methods to decrease power loss of wide band high power ferrite NiZn material are outlined as follow.Power loss of wide RF band high power NiZn ferrite material changes with the Fe amount of the composition. Less Fe amount within a range composition is suitable to get a low power loss under wide band RF high power application.Doping Co2O3,V2O5 can decrease power loss of RF band high power NiZn ferrite materialFactors mentioned above influence property of conveying wide band RF high power signal differently. It is necessary to find the best composition and processing. Thus, the wide band RF high power ferrite material works well.By increasing ball milling time and high temperature pre-sintering and low temperature sintering, the power loss of wide band RF high power ferrite material can be decreased.In application to convey high frequency high power signal, the performance of wide band RF high power NiZn ferrite material is estimated by power loss factor but Q factor. Because power loss factor is measured under high magnetic field, while Q factor is under low magnetic field. The higher the Q factor is,the less the power loss density is.
