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.
