遇到相同问题,用的是15版的,貌似help中是这样说的TLine to TLine Transforms (Kuroda Identities)
The TLine to TLine transforms are typically used to transform series short-circuited stubs to parallel open circuited stubs in preparation for implementation in planar transmission line technologies. However, these operations only work on Unit Element lines with electrical lengths of 45 degrees. Therefore, when performing lumped to ideal distributed transformations, you must perform substitutions that conform to this Unit Element specification. Preferred stubs (highlighted in blue on the graphical area) as well as series transmission lines (transformed with the Unit Element box checked) can be transformed in this way. When adding transmission line elements before or after the network, the electrical length is 45 degrees and only the characteristic impedance must be specified. However那一句说明只能用45度单位元件,而带阻带通貌似不用45度的线长吧。纯属个人观点,有误勿怪 |
