Remark: Reference level for the relative attenuation arel of the TFS 167D 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 temperature coefficient of frequency Tcf is valid for both the
reference frequency fc and the frequency response of the filter in the operating temperature range.

*) 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.
**) a power of 20 dBm can be applied shortly, for 10 years life time the cycle time should be less than 1:100
