Remark:

The minimum of the pass band attenuation a

is defined as the insertion loss a . The centre frequency f is the frequency of the minimum of the

passband attenuation a_min. The tolerance for the centre frequency also includes a frequency shift due to the temperature coefficient of frequency TC in the

operating temperature range and a production tolerance for the centre frequency f
