1/5
Measurement Condition
Ambient temperature:
23 C
Input power level:
0 dBm
Source impedance:
50 single ended
Load impedance:
50 single ended
Terminating impedances: *) input: 1,03 k // -15,4 pF
output: 0,88 k // -14,8 pF
Characteristics
Remark: Reference level for the relative attenuation arel of the TFS 125H is the minimum of the pass band attenuation. Reference for the echo
response attenuation is the main time response lobe, the reference time is defined as t0. The nominal frequency fN is fixed at 125 MHz without
tolerance. The given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below even
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.

reference values only. Should there be additional questions, do not hesitate to ask for an application note or contact our design team.
