HIGH FREQUENCY DEVICES
DIELECTRIC RESONATORS–DRD & DRT
R Series
GENERAL CHARACTERISTICS
I
High unloaded Q — 12,000 min. @ 10GHz.
I
High dielectric constant —
r
30.
I
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.
I
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).
