Characteristics

Remark:

Reference level for the relative attenuationarel of the TFS 167F is the minimum of the pass band attenuation amin. The maximum of the pass band

attenuation is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 2 dB filter

attenuation level relative to the insertion loss ae. The nominal frequencyfN is fixed at 167 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 even 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.
