This paper presents a simple method for implementing tunable diplexer. The tunable diplexer is formed by cascading a bandpass filter with a compact hybrid-coupled filter module (HCFM), thereby simplifying the tuning complexity of diplexers. Particularly, the bandwidths and center frequencies of the diplexer can be modified by simply tuning the center frequencies of the bandpass filters and/or the HCFM. Tunability of the diplexer is investigated considering different scenarios. Moreover, the concept is validated through measurement results of two cascaded designs. Only the center frequencies of the bandpass filters in the cascaded systems are different. As expected, the resulting two diplexers have different center frequencies and bandwidths for each channel. Measurements results agree well with EM simulations for both designs.
