Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 620 is the minimum of the pass band attenuation. This value 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 620 MHz without any tolerance. The values of relative attenuation arel are guaranteed for the whole operating
temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
