TFS 170 L
1/5
______________________________________________________________________________________________________
Measurement condition
Ambient temperature: 23 °C
Input power level:
0 dBm
Terminating impedance:
source:
1,47 kΩ || -7.1 pF
load:
610 Ω || -9,9 pF
Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 170 L 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 nominal frequency fN is fixed to 170,6 MHz. The given values for the relative attenuation
arel and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency fc is shifted due to the temperature
coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the centre frequency fc.
