Characteristics
Remark:
The maximum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency f_N is fixed at 748,0 MHz without any tolerance or
limit. The values of absolute attenuation aabs are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating
temperature range is included in the production tolerance scheme.
