2006 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedance: Input: Output: 23 0 50 50 °C dBm Ω Ω Filter specification TFS 1237 1/5 Characteristics Remark: The maximum attenuation in the pass band is defined as the insertion loss ae.
The nominal frequency fN is fixed at 1237 MHz without any tolerance or limit.
The values of absolute attenuation aabs 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.
