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.
