Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 321 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 321,4 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.

History
Version 1.0 1.1 1.2 1.3 Reason of Changes Generation of specification according to customer requirements. Change matching from balanced driven to unbalanced driven. Remove termanation impedance values. Change from development specification to filter specification. Add values for terminating impedance and coupling coil. Use harder conditions for vibration and damp heat Increase input power level from 10 dBm to 13 dBm Name Dr. Wall Dr. Wall Dr. Wall Herrler Date 22.03.2001 28.03.2001 18.06.2001 30.07.2001
