Remark:

The maximum attenuation in the pass band is defined as the insertion loss a . The nominal frequency f_Nis fixed at 1255 MHz without any tolerance or limit.

The values of absolute attenuation a

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

abs

temperature range is included in the production tolerance scheme.
