<p>A tunable electrical filter (10) constructed pursuant to the teachings of the present invention includes: (a) a plurality of resonator units (14, 16, 18) coupled between an input locus (12) and an output locus (13); and (b) a plurality of tunable dielectric varactor units (20, 22, 24, 26) ; first selected individual varactor units (24, 26) of the plurality of varactor units being coupled between respective pairs of the plurality of resonator units (14, 16, 18). Second individual varactor units (20, 22) are coupled between the plurality of resonator units (14, 16, 18) and the input locus (12), and coupled between the plurality of resonator units (14, 16, 18) and the output locus (13).</p> |
