Characteristics :
Remark: Reference level for the relative attenuation arel of the TFS 38C 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 centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 20 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 38 MHz without tolerance. The temperature coefficient of frequency Tcf is valid both for the reference frequency fc and the frequency response of the filter. All specified parameters have to be reached in the operating temperature range ( OTR ) .
