| TFS71D 09/97 __________________________________________________________________________________ Specification TFS 71 D - Page 1/3 VI TELEFILTER __________________________________________________________________________________ 1. Measurement Condition Ambient temperature TA: Input power level: Source impedance: Load impedance: 23 0 50 50 C dBm (refer to page 2) (refer to page 2) 2. Construction and Pin Configuration see page 2 3. Characteristics Remark: Reference level for the relative attenuation arel and the band width BW of the TFS 71 D 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 center frequency fo is the arithmetic mean value of the upper and lower frequencies at the 1,5 dB filter attenuation level relative to the insertion loss ae.
