Filter Specification
TFS 400 D - 1/4
______________________________________________________________________________________________________
Application
The filter is suitable for GSM, DCS 1800 and dual band applications. It can especially be used in the first IF in which full
channel selectivity is not necessary. The filter is very compact, thus it saves cost and space on the printed circuit board.
Measurement condition
Ambient temperature:
25
°C
Input power level:
10 dBm
Terminating impedances
for input:
600
|| 90 nH
for output:
600
|| 90 nH
coupling coil 56 nH
Construction and pin configuration

Characteristics
Remark:
Reference level for the relative attenuation arel of the TFD 400 D 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 center frequency fo 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 400 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 center frequency fo is shifted
due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the center frequency
fo.
