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 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.
