Characteristics

Remark:

attenuation is the main time response lobe, the reference time is defined as t

The given values for the relative attenuation a rel and for the group delay ripple have to be reached at the frequencies given below even if the

centre frequency f c is shifted due to the temperature coefficient of frequency TC f in the operating temperature range and due to a production

tolerance for the centre frequency f c .
