TFR 868C 1/5
Measurement condition
Ambient temperature:
23 C
Input power level:
10 dBm
Terminating impedances :
for input: 50 || 0 pF
for output: 50 || 0 pF
Characteristics
Remark:
The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fc is the measured frequency at
the minimum insertion loss point.
