Abstract :
Methods of tunable filters spurious response improvement are described. Dielectric resonator based filters with ferrite elements suffer from spurious resonances located close to the useful passband. Optimization of the resonator structure as well as application of TEM resonators leads to significant improvement. Design methods and measured results are provided.
