Characteristics

Remark:

The reference level for the relative attenuation arel of the TFS340B is the minimum of the passband attenuation amin. The minimum of the passband

attenuation amin is defined as the insertion loss ae. The nominal frequency fN is fixed at 340MHz without any tolerance. The values of the relative

attenuation arel are guaranteed over the whole operating temperature range. The frequency shift of the filter within the operating temperature range is

included in the production tolerance scheme.
