Characteristics
Remark:
The minimum of the attenuation amin is defined as the insertion loss a_e. The centre frequency f_R is the measured frequency at the minimum insertion loss
point. The frequency shift of the filter in the operating temperature range is not included in the production tolerance scheme.
