Characteristics
Remark:
The nominal frequency fN is fixed at 160 MHz. The insertion loss ae is defined as loss value determined at fN. Reference level for the relative attenuation
arel of the TFS 160G is the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 35 dB filter
attenuation level relative to the insertion loss ae. All specified data are met within the operating temperature range.
