Abstract
This paper presents a rigorous approach to design a bandpass filter with a wide spurious-free upper stopband. One of the unique features of the presented design method is that a spurious-free upper stopband range can be determined in advance. The presented design approach requires no coupling tests heavily relying on time-consuming electromagnetic simulations. For illustration, we have designed, fabricated, and measured a 4th-order microstrip Chebyshev filter. The second passband was defined to be at 8f0 (f0 : center frequency of the primary passband) so that the filter has a spurious-free region from f0 to 8f0.
