Dielectric Filters
Token Offers Dielectric RF Filters
for Telecoms (DF-A)
Preview
Token has extended the capabilities of its
filter product line with the introduction of a
new range of dielectric microwave filters to
the available frequency range up to 5.8GHz.
Token designs and manufactures custom
electronic filters for defence,
telecommunications and similar application
increasing the range of products available to
customers.
Two block-type dielectric RF filters for
telecoms basestation applications have been
added to Token’s DF range. The filters have been designed for cellular basestation applications that use a digital
pre-distortion amplifier (DPD), as they feature a wide pass band and flat ripple performance, which are required
for DPD PA design.
Applications also include RF and microwave communications such as GSM, 3G, GPS, satellite and TV
transmission, wireless security systems, radar, CT1, CT2, 900MHz, 1.8GHz, 2.4GHz, 5.8GHz Cordless Phone,
wireless earphone, wireless microphone, aerospace and military.
The DF-A filter’s small size (8.8 x 7.3 x 3.6 mm) means they require more less mounting space compared to
Token’s previous generation of filters for this application. The filters’ highly sophisticated multi-pole design
ensures high attenuation and good selectivity. Both the two members of the DF series have a ripple of 1.0 dB
max.
In addition, Token enhances custom design capabilities for specialist applications. Our customers will benefit
from the additional frequency ranges now available and from the excellent quality and lower costs achievable
Custom parts are available on request. Token will also produce devices outside these specifications to meet
specific customer requirements, please contact our sales for more information.
Applications
- Suitable for surface mount and reflow soldering.
- Excellent mechanical structure and temperature stability.
- Good selectivity, low insertion loss for using high Q-value resonators.
