Characteristics
Remark:
The maximum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 1228.8 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.
