TFS112H

tfs112H.doc Version 1.3 14.02.2001 VI TELEFILTER Filter Specification TFS 112H - 1/5 1. Measurement condition : Ambient temperature TA: Input power level: Terminating impedances at fc: Q-value of matching elements: 23 °C 0 dBm. for input: for output: 50...70 565 Ω  - 6,5 pF. 650 Ω  - 5,7 pF. 2. Characteristics : Remark: Reference level for the relative attenuation arel of the TFS 112H is the minimum of the passband attenuation amin. The minimum of the passband 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 30 dB filter attenuation level relative to the insertion loss ae.
