Characteristics

Remark:

tolerance. The given values for the absoult attenuation ae have to be reached at the frequencies given below even if the centre frequency fc is

shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the centre

frequency fc.
