1. Measurement condition
Ambient temperature: 23 °C
Input power level:
0 dBm
Terminating impedances*
for input: 200 Ω
for input: 200 Ω
2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 1220B 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 nominal frequency fN is fixed at 1220,0 MHz without tolerance. The
temperature coefficient of frequency Tcf is valid both for the frequency fc and the frequency response of the filter in the operating temperature
rang.
