tfs440.doc version 1.3 15.06.2000 VI TELEFILTER Filter specification TFS 440 - 1/5 Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Terminating impedances for input: 250 // -0.8 pF for output: 250 // -0.8 pF Characteristics Remark: Reference level for the relative attenuation a of the TFS 440 is the minimum of the pass band attenuation a . The minimum of the pass band rel min attenuation a is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at min e c the 3 dB filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed on 440 MHz without tolerance. The given values e N for the relative attenuation a and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency f is rel c shifted due to the temperature coefficient of frequency TC in the operating temperature range and due to a production tolerance for the centre f frequency f . c D a t a typ.
