Abstract :
A compact high linearity microstrip dual-mode tunable filter is proposed. The characteristics of the dual-mode tunable resonator are investigated. Methods of minimising the change in bandwidth across the frequency shift are discussed. A tunable filter was demonstrated experimentally to verify the argument where a 35 % shift in the pass-band was observed, with a 5.2 % change in bandwidth.
