Abstract

An adjustable filter includes an outer conductor, a first inner conductor, and a second inner conductor. The inner conductors are capacitively coupled on the same axis. The further may further include a third inner conductor capacitively coupled to both the first and second inner conductor. The third inner conductor is axially displaceable with respect to the first and second inner conductors. With this configuration, generation of intermodulation products can be minimized.
