Black Custom Bandpass Filter RF Cavity Filter In Telecom Parts
1 Operating principle about bandpass filter
An ideal bandpass filter should have a completely flat passband, no amplification or attenuation in the passband, an active bandpass filter circuit and all frequencies outside the passband are completely attenuated, in addition, the conversion outside the passband is completed in a very small frequency range.
In fact, there is no ideal bandpass filter.The filter cannot attenuate all frequencies outside the desired frequency range, especially if there is a range outside the desired passband that is attenuated but not isolated.This is often referred to as the rolling down of the filter and is represented by the dB number of the attenuation amplitude per tenfold frequency.Generally, the design of the filter is as narrow as possible, so that the performance of the filter is closer to the design.
