VI TELEFILTER
SAW Filter Specification
TFS 400 B
1/5
_____________________________________________________________________________________________________
Application
The filter is suitable for GSM, DCS 1800 and dual band receivers. It can especially be used in the first IF in which full channel
selectivity is not necessary. Due to the high frequency the filter is small, thus it saves cost and space on the printed circuit
board. As it has symmetrical input and output it does not need any transformation networks in state of the art IC transceiver
concepts in which symmetrical inputs and outputs are favourable.
Measurement condition
Ambient temperature: 23 °C
Input power level:
10 dBm
Terminating impedances
for input: 580 ohms || -0.72
for output: 580 ohms || -0.72
ext.coil:
47 nH

Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 400 B 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 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 centre 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 centre frequency fo.
