VI TELEFILTER
Filter Specification
Version 1.0
25.07.2000
TFS 70H12A - 1/4
1. Measurement condition
Ambient temperature TA:
Input power level:
Terminating impedances in fc:
25 °C.
0 dBm.
for input:
for output:
50 Ω 0 pF.
50 Ω 0 pF.
2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 70H12A 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 reference frequence fc is the arithmetic mean value of the upper and lower
frequencies at the 20 dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid both for the
reference frequency fc and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating
temperature range is not included in the production tolerance scheme.
