13.06.01
- 1/5
Measurement condition
Ambient temperature:
23 °C
Input power level:
0 dBm
Terminating impedances
for input: 50 Ω || 0 pF
for output: 50 Ω || 0 pF
Characteristics
Remark:
The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fR is the frequency of the minimum of the
passband attenuation amin. The temperature coefficient of frequency TRF is valid both for the resonant frequency fR and the frequency response of
the resonator in the operating temperature range. The frequency shift of the resonator in the operating temperature range is not included in the
production tolerance scheme.
