The filter supports bursted GMSK and EDGE modulation.
Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 211-1 is the filter attenuation at 211 MHz. The filter attenuation at 211 MHz is called 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 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.
