Characteristics

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

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
