Characteristics
Remark:
The reference level for the relative attenuation arel of TFS140W is the minimum of the pass band attenuation amin. 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 f_N is fixed at 140 MHz without tolerance. The given values are guaranteed in operating temperature range.
