This paper presents a symmetric reflectionless filter topology that is capable of producing the canonical Butterworth responses with zero reflections at both ports. Straightforward design methods of a coupled-line bandpass filter using the newly synthesized filter topology are also given. Hence, a filter can be designed analytically without relying on a time-consuming numerical method. The measured frequency responses are in a good agreement with the synthesis.
