BP-R Dielectric Bandpass Filters

Preview

Dielectric bandpass filters, known as ceramic bandpass filters, dielectric ceramic filters, or microwave ceramic

filters in standard resonator sizes. Token BP-R series center frequency range is from 915 MHz to 1220 MHz

basic rules of ceramic band-pass filters and diplexer. Insertion loss is from 2.0 ~ 3.5 (dB) max and a ripple in

bandwidth 0.5 (dB) max.

The higher the Q-factor of a resonators/band pass filters, the better electrical performance for insertion loss. The

more dielectric resonators combined together for a band pass ceramic filters, the better rejection, attenuation, and

stopband will be. Determinant factor for Insertion Loss Q factor of a resonator, the bandwidth of a filter, and the

number of resonators Determinant factor for Attenuation/rejection The number of resonators, connection type of

resonators.

Token RF ceramic bandpass filters can be customed designs and tighter tolerances available on request. Token

BP-R series are primarily designed for high dielectric constant lines and conform to the RoHS directive.

The (BP-R) series feeature with high permittivity, high dielectric constants, extremely temperature stability and

high Q that enables the design of stable microwave oscillators and filters. High dielectric constant (K) materials

and associated products are also available for custom application requirements.

Please contact our sales for more information.
