BS EN 60556:2006+A1:2016描述了根据IEC 60392规定的多晶微波铁氧体和铁氧体技术通用性能的测量方法。这些测量方法用于研究微波频率下的材料(通常称为铁氧体)。单晶和薄膜通常不在本标准的范围内。注1:就本标准而言,“铁氧体”和“微波”这两个词在广义上使用:“铁氧体”不仅指具有尖晶石晶体结构的磁介质化学成分,还指具有石榴石和六角结构的材料;
“微波”区域包括大约1米到1毫米的波长,主要关注的是0.3米到10毫米的区域。注2:使用微波铁氧体的组件示例为非互易装置,如环行器、隔离器和非互易移相器。这些构成了主要的应用领域,但这些材料也可用于互易器件,例如调制器和(互易)移相器。其他应用包括旋磁滤波器、限制器和更复杂的设备,如参数放大器。

BS EN 60556:2006+A1:2016 describes methods of measuring the properties used to specify polycrystalline microwave ferrites in accordance with IEC 60392 and for general use in ferrite technology. These measuring methods are intended for the investigation of materials, generally referred to as ferrites, for application at microwave frequencies.Single crystals and thin films generally fall outside the scope of this standard.NOTE 1 For the purposes of this standard, the words "ferrite" and "microwave" are used in a broad sense:by "ferrites" is meant not only magneto-dielectric chemical components having a spinel crystal structure, but also materials with garnet and hexagonal structures;the "microwave" region is taken to include wavelengths approximately between 1 m and 1 mm, the main interest being concentrated on the region 0,3 m to 10 mm.NOTE 2 Examples of components employing microwave ferrites are non-reciprocal devices such as circulators, isolators and non-reciprocal phase-shifters. These constitute the major field of application, but the materials may be used in reciprocal devices as well, for example, modulators and (reciprocal) phase-shifters. Other applications include gyromagnetic filters, limiters and more sophisticated devices, such as parametric amplifiers.Cross References:IEC 60050-221IEC 60205:2006IEC 60392:1972EN 60205:2006Incorporates the following:Amendment, June 2016.
