Measurement condition

Ambient temperature T

23 °C

Input power level:

0 dBm

Terminating impedances at fc *):

input: 1840 // -10,1 pF

output: 2170 // - 9,8 pF

Characteristics

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.

**) This power level is only allowed for short term operation (10% of the life time), the max. input power for continuous operation is only

max.15dBm
