Characteristics
Remark:
The nominal frequency fN is fixed at 491,52 MHz. The insertion loss ae is defined as loss value determined at fN. Reference level for the relative
attenuation arel of the TFS 491A is the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the
dB filter attenuation level relative to the insertion loss ae. All specified data are met within the operating temperature range.
