Remark:  
Reference level for the relative attenuation a of the TFH 70F is the insertion loss. The insertion loss a is defined as the insertion loss at the  
rel

nominal frequency f . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level  
N
relative to the insertion loss a . The given values for the insertion loss, the relative attenuation a and the group delay ripple have to be reached  
e
rel  
at the frequencies given below also if the centre frequency f is shifted due to the temperature coefficient of frequency TC in the operating  
temperature range and due to a production tolerance for the centre frequency f .
