Abstract
Techniques for implementing tunable lumped element filters with transmission line sections. Transmission lines sections are used to implement one or more inductive or capacitance component elements of the filter. The filter is tunable by changing the dielectric constants of the transmission lines. In particular implementations there is an individual transmission line section for each lumped element component of a filter. Different filter circuits may be combined to provide a universal tunable filter assembly.
