HIGH FREQUENCY DEVICES
DIELECTRIC RESONATORS–DRD & DRT
U Series
GENERAL CHARACTERISTICS
ꢀ High unloaded Q — 6,000 min. at 7GHz.
ꢀ High dielectric constant — ꢁr ꢀ 38.
ꢀ Resonant frequency temperature coefficient from –4 to
+10ppm/°C.
ꢀ Accurate and repeatable dielectric constant ( 0.5).
ꢀ Improved spurious response (spurious modes are further
removed from fundamental resonant frequency).
ꢀ Decoupled mounting on supports above substrate
maximizes operational Q.
