| TFS70F.doc __________________________________________________________________________________ VI TELEFILTER Filter specification TFS 70 F - 1/3 __________________________________________________________________________________ Package, pin connection and 50 matching network see page 2. Version 2.2 06.01.02 1. Measurement condition Ambient temperature TA: 25 C Input power level: 0 dBm (typ.) Max 10 dBm. Terminating impedances at fc: for input: 53 -40 pF. for output: 54 -40 pF. 2. Characteristics Remark: Reference level for the relative attenuation arel of the TFD 70F 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 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. The frequency shift of the filter in the operating temperature range is not included in the production tolerance scheme.
