Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 125C is the maximum of the pass band attenuation amax. The maximum of the pass
band attenuation amax is defined as the insertion loss ae. The centre frequence fc is the arithmetic mean value of the upper and lower frequencies
at the 1 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 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 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.

History
Version Reason of Changes
Name
1.0 - generation of specification according to hudson specification
Sabah
1.1 - correction according to customer specification (Nokia)
Sabah
- IP3: instead of ‘No statement’ is ≥ 60 dBm
- VSWR (max): instead of ≤ 2.0:1 is ≤ 2.3:1
- Rejection (f ≥ fN ± 13000 KHz): instead of min. 60 dB is
min. 55 dB
- Operational temperature range changed from -10 .... 80 °C to -10 ..... 85 °C
1.2 - The sprocket holes: instead of the right side of the tape is on the left
side of the tape (according to customer requirement, e mail from: 7. Juli.00)
