We can offers Ceramic Bandpass Filters(also called dielectric filters, or dielectric ceramic filters,microwave ceramic filters) in standard resonator sizes of 2mm , 3mm , 4mm , 5mm , 6mm , 8mm , 10mm and 12mm (normally 3mm , 4mm , 5mm , 6mm , 8mm ).
Bandwidth: 0.5% to 8% of center frequency
Basic rules of ceramic band-pass filters and diplexersp
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/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
