| TFS87.doc __________________________________________________________________________________ VI TELEFILTER Filter specification TFS 87 1/3 __________________________________________________________________________________ 1. Measurement condition Package, pin connection and 50 matching network. see page 2. Version 1.2 06.01.02 Ambient temperature TA: 23 C Input power level: 0 dBm (typ.) Max 10 dBm. Terminating impedances at fc: for input: 256 - 22,5 pF. for output: 703 - 11,8 pF. 2. Characteristics Remark: Reference level for the relative attenuation arel of the TFS 87 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 reference 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.
