ADS端口加边缘有明确的规定,端口加边缘的时候,铜皮边缘宽带若高于仿真频率波导波长的1/10,则仿真结果可能出现问题(Momentum enforces a constant potential over the entire edge or area pin. This assumption is only valid when the length of the edge pin or the diameter of the area pin is electrically small. Rule of thumb is that the size is smaller than 1/10 of the wavelength at the highest frequency.Failing to comply with these restrictions may lead to unphysical S-parameters.)。
以BLC2425M9XS250 使用0.762mm的罗杰斯4003为例,2.45GHz十分之一波导波长为7.45mm,但是该管子的栅极漏极金属片宽度大12.83mm,这样超过了端口加边缘的尺寸限制,这样仿真结果会出问题吗,怎么解决。
