Characteristics
Remark:
The nominal frequency fN is fixed at 307,20 MHz. The insertion loss ae is defined as loss value determined at fN. Reference level for the relative
attenuation arel of the TFS 307 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.
