Characteristics

Remark:

Reference level for the relative attenuation a rel of the TFS 221A is the insertion loss. The minimum of the pass band attenuation a min is defined as

the insertion loss a e . The centre frequency f c is the arithmetic mean value of the upper and lower frequencies at the 1 dB filter attenuation level

relative to the insertion loss a e . The temperature coefficient of frequency Tc

of the filter in the operating temperature range.
