摘要
This paper proposes a novel quadruple-mode cavity resonator and filters. The cavity resonator Involves four modes which are similar in frequency and can be easily controlled. Meanwhile 20% volume saving can be achieved while maintaining the similar unloaded Q-factor value of the conventional designs. Moreover, as the electric field of proposed modes only exist horizontal component, the four modes can be simulated by using a pair of mental probes without any other intra-cavity coupling structure. To demonstrate the new resonator technology, a four-pole filter with 40 MHz wide filter at 2.6GMHz is designed and simulated.
