Dielectric Bandpass Filters (BP-R) Series

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.
