Characteristics
Remark:
The minimum of the attenuation amin is defined as the insertion loss a_e. The centre frequency f_c is the measured frequency at the minimum insertion loss
point. The tolerance for the centre frequency also includes a centre frequency shift due to the temperature coefficient of frequency TCf in the operating
temperature range and a production tolerance.
