摘要：

Classic formulas for designing direct-coupled band-pass filters are very well-known and widely used. In this paper, such formulas are used in a non-conventional way to overcome some manufacturing limits of coupled-line planar filter implementations. This technique is validated through the design of two prototypes with extremely wide band and high return loss specifications: a classical filter on the resolution limit of standard PCB manufacturing processes and its enhanced counterpart. The measured prototypes demonstrate the feasibility of this method.
