Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 150C1 is the minimum in the usable signal bandwidth. The maximum attenuation amax in the
usable signal bandwidth is defined as the insertion loss ae. The reference frequency fc is the arithmetic mean value of the upper ( f_6dB+ ) and lower (f_6dB-)
frequencies at the 6 dB filter attenuation level relative to the insertion loss ae . The nominal frequency fN is fixed at 150,4 MHz without tolerance. The
usable singnal bandwidth has to be guaranteed 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

*) The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as reference values
only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
