ABSTRACT Rigorous mode matching method, incorporating the perturbation techniques was introduced to the modeling, analysis and design of the resonant frequency-temperaturecharacteristic of the combline resonator. Methods for temperature compensation of the resonator are accurately modeled and implemented. The accuracy of the modeling results is verified by comparing with the measured results and shown to be in good agreement. I. INTRODUCTION Combline resonators and filters have been widely used in many communication systems and microwave applications because of their many u
