GENERAL CHARACTERISTICS
I High unloaded Q — 20,000 min. @ 10GHz.
I High dielectric constant —
r
24.5.
I The resonant frequency temperature coefficient can be
chosen from 0 to 6ppm/°C. Tolerance of frequency
temperature coefficient can be chosen ±1, ±2ppm/°C.
I Dielectric resonators are chosen from the frequency
range of 8.4 to 25GHz in disk type (DRD), and from the
frequency range of 8.4 to 19.5GHz in cylindrical type (DRT).
I E-Series is also fit for application above 25GHz. Please
consult us.
