2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 36A is the minimum of the pass band attenuation amin. The minimum of the pass band
attenuation amin is defined as the insertion loss ae . The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the
40 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 36 MHz without tolerance. The temperature
coefficient of frequency Tcf is valid both for the reference frequency fc and the frequency response of the filter in the operating temperature range. The
frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
