Remark:  
The maximum attenuation in the pass band is defined as the insertion loss a . The nominal frequency fN is fixed at 1237 MHz without any tolerance or limit.  
e
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.
