Remark:

The maximum attenuation in the passband is defined as the insertion loss a . The nominal frequency f_Nis fixed at 1250 MHz without any tolerance or

limit. The values of absolute attenuation

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

abs

operating temperature range is included in the production tolerance scheme.
