HIGH FREQUENCY DEVICES
DIELECTRIC RESONATORS–DRD & DRT
V Series
GENERAL CHARACTERISTICS
ꢀ High unloaded Q – 7,000 min. at 10GHz
ꢀ High dielectric constant – ꢀr ꢀ 34
ꢀ Resonant frequency temperature coefficient can be
chosen from 0 to 6ppm/°C. Tolerance of frequency
temperature coefficient can be chosen from 0.5, 1,
and 2ppm/°C.
