tfs 120C.doc Version 1.0 06.01.02 VI TELEFILTER Filter specification TFS 120 C 1/4 1. Measurement condition Package, pin connection and 50 Ω matching network Ambient temperature TA: 23 °C Input power level: 0 dBm for input: 1270 Ω  -11,7 pF. Typical terminating impedances in fN: for output: 4330 Ω  -2,9 pF. (see sheet 2.) 2. Characteristics Remark: Reference level for the relative attenuation arel of the TFS 120C 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 120,0 MHz without tolerance or limit. The reference frequence fc is the arithmetic mean value of the upper and lower frequencies at the 40 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.
