DF-C/D Dielectric Filters

Preview

Token two block-type dielectric RF 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 satellite and TV transmission, wireless

security systems, radar, GSM, 3G, GPS, CT1, CT2, 900MHz, 1.8GHz, 2.4GHz, 5.8GHz Cordless Phone,

wireless earphone, wireless microphone, aerospace and military.

The (DF-C/D) filter’s small size (4.5 x 4.5 x 2.0 mm) means they require more less mounting space with a ripple

of 1.0 dB max and insertion loss 2.0 (dB) max. Center frequency range from 1575 MHz to 5800 MHz with

V.S.W.R 2.0 max.

The surface mount RF Dielectric Filters (DF-C/D) conform to the RoHS directive and package is suitable for

automatic pick and place equipment which assures mechanical stability and excellent lead coplanarity. Customed

designs and tighter tolerances are available on request. Application of specific designs also available including

different Dielectric values and Q specifications adjusted to frequency requirements.
