Characteristics
Remark:
The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fC is the frequency of the minimum of the
passband attenuation a
min
. The tolerance for the centre frequency also includes a frequency shift due to the temperature coefficient of frequency TCf in the
operating temperature range and a production tolerance for the centre frequency fC.
