Product Introduction
Token Offers Dielectric RF Filters for Telecoms.
Features :
Suitable for surface mount and reflow soldering.
Excellent mechanical structure and temperature stability.
Good selectivity, low insertion loss for using high Q-value resonators.
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 defense,
telecommunications and similar application increasing the range
of products available to customers.
Two block-type dielectric RF filters for telecoms base station
applications have been added to Token's DF range. The filters
have been designed for cellular base station 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 × 7.3 × 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, contact us with your specific needs. For more information,
