CERAMIC COAXIAL RESONATORS
General characteristics
APPLICATIONS
TEMEX coaxial ceramic resonators provide the users with “High Q” higher parallel resonant
impedance and better temperature characteristics than inductor coils and associated lumped constant
elements used in RF ampliers and oscillators circuits.
These coaxial resonators are perfectly suitable for:
DRO/VCO oscillators
Cordless telephone
Cellular telephone
Tuned oscillators
UHF (LC) coupled ampliers
Narrow band lters
Global Positioning Systems (GPS)
Duplexers
