Constant-resistance filters with diplexer architecture for S-band applications

—Constant-resistance filters are a class of absorptive filters that ideally present no reflection to the incoming signal of any frequency while their transfer function can be designed to exhibit low-pass, high-pass or band-pass characteristics. There is a variety of architectures employed to accomplish this function and such filters are used for terminating the output stages of amplifiers and mixers. In this work, we discuss the design of low-pass reflectionless filters employing a diplexer architecture with the intent to separating the useful signal (low-pass) from the higher harmonics which will be terminated externally to the filter.
