There are also standards that do not have a Inter-pair skew requirement because the different lanes do not have to be the same length. · Insert substrate parameters: H=1270um, T=12. If you're an employee, then you pay one half of this total (probably as a withholding on your paycheck); your employer pays the other half for you (and then gets a deduction for their half on their corporate tax return, since it's an expense - for them it's as if the FICA "half" is an additional piece of salary). Both lines are less that 1/2-wavelength. Both open and short-circuited stubs are employed in this type of stub matching. When working with a fixed frequency this is not an issue, however if multiple frequencies must be supported, designing a double stub tuner may be desirable. Z0s ls Apr 23, 2014 · Thank you so much.
