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