2. Characteristics

Remark:

Reference level for the relative attenuation arel of the TFD 70 Q is the m inim um of the pass band attenuati on amin. The minim um of the pass band

attenuation amin is defined as the insertion loss ae. The reference frequency fc is the arithmetic mean value of the upper and l ower frequencies at

the 20 dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid both for the reference

frequency fc and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating temperature

range is not included in the production tolerance scheme.
