2. Characteristics

Remark:

Reference level for the relative attenuation arel of the TFD 70 Q is the minimum of the pass band attenuation amin. The minimum 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 lower frequencies at

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.
