VI TELEFILTER Filter specification TFS 400 A 1/4 ______________________________________________________________________________________________________
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: 0 dBm Source impedance: balanced 770 II - 0.8 pF Load impedance: balanced 770 II - 0.8 pF
Construction and pin configuration

Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 400 A 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 400,000 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.
