ABSTRACT:
A high-frequency filter having series and parallel electrode patterns formed on a mount substrate, surface acoustic wave resonators connected to a signal input/output line of the electrode patterns in series, and coaxial dielectric resonators having respective one input/output terminals connected to the signal input/output line and the other input/output terminals connected to a ground element. In such a composite high-frequency filter, the surface acoustic wave resonators form the resonators in the serial arms while the coaxial dielectric resonators form resonators in the parallel arms. The high-frequency filter can meet all the requirements of enhanced miniaturization, selectivity and power handling.
