Dielectric Filters
(DF 3 or Multi-Pole)
Dielectric Filters (DF) 3 or multi-pole range up to 5.8GHz
Preview
The dielectric filter technology based on high Dielectric Constant (K) ceramic material has been contributing
great size reduction of a mobile telecommunication equipment, especially cellular handset and base station. That
is superior in electrical performances and reliability. Furthermore it has good mass productivity and low cost.
Token (DF) dielectric filters’ highly sophisticated multi-pole design ensures high attenuation and good selectivity.
The (DF) multi-pole series filter’s small size (8.6 x 9.0 x 3.0 mm) means they require more less mounting space
with a ripple of 1.0 dB max. Insertion loss is from 2.0 ~ 3.5 (dB) max. Center frequency range from 860 MHz to
5800 MHz with V.S.W.R 2.0 max.
Coaxial dielectric filter is the most popular and commercially successful technology. Token takes this advance
technology to manufacture coaxial type duplexer. This features high unloaded Q, excellent high power
performance, flexible design capability, size reduction, low profile, and lighter weight.
Surface mount multi-pole (DF) serise RF filter package is suitable for automatic pick and place equipment which
assures mechanical stability and excellent lead coplanarity. Custom designs and tighter tolerances are available
on request. Products conform to the RoHS directive.
Token will also produce devices outside these specifications to meet specific customer requirements, please
contact our sales for more information.
