The blue line has 15khz bandwith and the red line has 6khz bandwith.
What is ceramic bandpass filter.
Band pass filters ceramic band pass filters skyworks is a world class supplier of high performance ceramic band pass filters.
They may also be used as resonant elements in a variety of electronic circuit designs often being used in fm demodulators.
The definition of the bandwith of a ceramic filter is the frequency gap where the signal has dropped less than 6db.
The ceramic filter is a passive bandpass element which passes frequencies in a narrow band called the pass band centered at about 10 7 mhz and rejects all others in two regions called the stop bands above and below the passband in frequency.
Specializing in band pass notch and diplexing applications skyworks can cover a frequency range from 250 mhz to 7000 mhz with surface mount or connectorized devices.
The red line is sharper and dropps much faster.
A band pass filter or bandpass filter bpf is a device that passes frequencies within a certain range and rejects frequencies outside that range.
There is filter with just a few kiloherts of bandwith.
