Characteristics Remark: Reference level for the relative attenuation arel of the TFS 420A 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 nominal frequence fN is fixed at 420,0 MHz without tolerance or limit. The reference frequence fc is the arithmetic mean value of the upper and lower frequencies at the 3 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. Data typ. value tolerance / limit 21,5 dB max 24 dB Insertion loss (Reference level) ae 420,0 MHz Nominal frequency fN Centre frequency fc at ambient temperature ( fCAT ) 420,03 MHz Pass band (-1dB) fN - 4,1 MHz ... fN + 4,1 MHz 0,4 dB max 1,0 dB Amplitude ripple (p-p): fN ... fN ± 4,1 MHz Bandwidth at ambient temperature: 1 dB - band width 9,14 MHz 3 dB - band width 10,50 MHz 20 dB - band width 14,23 MHz 40 dB - band width 15,91 MHz Relative attenuation arel fN fN ± 4,1 MHz max. 1 dB MHz fN ± 5,0 MHz max. 3 dB fN ± 4,1 MHz fN ± 10 MHz min. 3 dB fN ± 5,5 MHz fN ± 100 MHz 45...60 dB min. 40 .
