Filter specification
TFS 420A - 1/4
1. Measurement condition Ambient temperature TA: 23 °C Input power level: 0 dBm for input: Typical terminating impedances in fN: for output:
210 Ω -5,38 pF. 174 Ω -3,99 pF.
2. Characteristics
Remark: Reference level for the relative attenuation arel of the TFS 420A 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 nominal frequence fN is fixed at 420,0 MHz without tolerance or limit. The reference frequence 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.
