Characteristics
Remark:
Reference level for the relative attenuation arel is the minimum of the pass band attenuation amin. The minimum of the pass band
attenuation amin is defined as the insertion loss ae. The nominal frequency fN is fixed to 85,38 MHz. The values given below shall be
met in the operating temperature range.
