1 VI TELEFILTER Filter specification TFS 188 1/5 Measurement condition Ambient temperature: 23 C Input power level: dbm Terminating impedances for input: 5 Ω for output: 5 Ω Characteristics Remark: The maximum attenuation in the pass band is defined as the insertion loss a e. The nominal frequency f N is fixed at 188 MHz without any tolerance or limit. The values of absolute attenuation a abs 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.
