Characteristics
Remark:
The maximum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 1255.0 MHz without any tolerance or limit.
The values of absolute attenuation aabs 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.
