TFS70H29

Reference level for the relative attenuation a_rel of the TFS70H29 is the minimum of the pass band attenuation a_min. The minimum of the pass band attenuation a_min is defined as the insertion loss a_e. The reference frequency f_c is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss a_e. The temperature coefficient of frequency Tcf is valid both for the reference frequency f_c 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
