TFS77B

Filename: tfs 77b.doc Version 1.2 12.05.2006 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedance: * Input: Output: 25 0 °C dBm Filter specification TFS 77B 1/5 48 Ω || 2,5 pF 44 Ω || 8,5 pF Characteristics Remark: The reference level for the relative attenuation arel of the TFS 77B is the minimum of the pass band attenuation. This value is defined as the insertion loss ae. The nominal frequency fN is fixed at 77,8 MHz without any tolerance. The values of relative attenuation arel are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
