Abstract: An adjustable microwave diplexer comprising two combline filter sections (A and B). Each filter section has at least three tunable resonator elements (1,2,3 and 4). Non-adjacent resonator elements of one section (A) are inductively coupl ed by an adjustable coupling element (20,21), and non-adjacent resonator elements of the other section (B) are capacitively coupled by an adjustable capacitor element (31). This arrangement provides the means to achieve adjustable transmission zeros above the passband of filter A and below the passband of filter B to provide the diplexer with two highly selective filters.
