Abstract:

A novel, high-Q, high-power VHFUHF bandpass filter is described that is electronically tuned according to a binary logic. A high-Q, TEM-line resonator is distributively loaded with N independent capacitive irises, such that the opening and closing of switches within each iris makes its capacitance two-valued. Mathematical modeling and design relations were developed and a working, 512-channel 9 iris bandpass filter was completed for the range 194 to 359MHz.
