Abstract :
A new class of dual mode filters is presented. These devices use conductor loaded dielectric resonators with unloaded Q factors of 2000-8000 achievable in half the physical size of TEM filters with good spurious performance. A design example of a transmit filter for a GSM cellular radio base station is demonstrated.
