tfs70H22.doc Version 1.1 04.03.2002 VI TELEFILTER Filter specification TFS 70H22 1/5 1. Measurement condition : Ambient temperature TA: Input power level: Terminating impedances in fc * ) : 25 °C. 0 dBm. for input: for output: 180 Ω ⎟⎢ - 17,6 pF. 240 Ω ⎟⎢ - 13,7 pF. 2. Characteristics : Remark: Reference level for the relative attenuation arel of the TFS 70H22 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. 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.
