HIGH FREQUENCY DEVICES
DIELECTRIC RESONATORS–DRD & DRT
R Series
GENERAL CHARACTERISTICS
ꢀ High unloaded Q —12,000 min. @ 10GHz.
ꢀ High dielectric constant — ꢁr ꢀ 30.
ꢀ The resonant frequency temperature coefficient can be
chosen from 0 to 6ppm/°C. Tolerance of the frequency
temperature coefficient can be chosen 0.5, 1 and
2ppm/°C.
ꢀ Dielectric resonators are chosen from the frequency
range of 4.6 to 24.2GHz in disk type (DRD), and from the
frequency range of 5.7 to 13.1GHz in cylindrical type (DRT).
