标准摘要
[中文适用范围]： IEC 60154的本部分规定了电子设备中使用的普通矩形波导的法兰尺寸。它涵盖了在波导上安装之前或之后钻孔的法兰要求。应该注意的是，为了获得最佳电气性能，建议在安装后钻对准孔。该标准的目的是为波导法兰规定必要的机械要求，以确保兼容性和尽可能的互换性以及确保足够的电气性能。 [外文原描述]： IEC 60154-2:2016 specifies the dimensions of flanges for ordinary rectangular waveguide for use in electronic equipment. It covers requirements for flanges drilled before or after mounting on waveguides. It should be noted that for optimum electrical performance, post-drilling of the alignment holes after mounting is recommended. The aim of this standard is to specify for waveguide flanges the mechanical requirements necessary to ensure compatibility and, as far as practicable, interchangeability as well as to ensure adequate electrical performance. This edition includes the following significant technical changes with respect to the previous edition: a) revise the estimation for return loss at connection interface of waveguides; b) add two type of waveguide flange for high frequency application, i.e. over 50 GHz; c) expand the operation frequency range up to 3,3 THz; d) rename the frequency band over R 1200, i.e. R1,2k.
