TFS70H312

Filename: tfs 70h312.doc Version 1.1 30.10.2006 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedance: * Input: Output: 25. 0 °C dBm Filter specification TFS 70H312 1/5 50 Ω || 0 pF 50 Ω || 0 pF Characteristics Remark: The reference level for the relative attenuation arel of the TFS 70H312 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 centre 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 for both 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.
