TFS 440 - 1/5
______________________________________________________________________________________________________
Measurement condition

23 °C
Input power level:
0 dBm
Terminating impedances
for input: 250 Ω // -0.8 pF
for output: 250 Ω // -0.8 pF
Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 440 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 centre frequency fc is the arithmetic mean value of the upper and lower frequencies at
the 3 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 440 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.
