Application of ADF5904 on frequency slightly higher than specifications in datasheet

Hi,

 

I like to down-convert a narrow band signal (1 MHz bandwidth) with carrier frequency of 24.750 GHz to an IF frequency of less than 10 MHz.

 ADF5904 is the perfect solution for my system. But unfortunately the datasheet does not state its performance on frequencies higher than 24.250 GHz .

 

Is there any filter inside the chip which prevents application of higher RF and LO frequencies or I can safely use this chip for my application?

What would be the expected degradation in gain and required LO drive power in the case of operation for 24.750 GHz?

 

many thanks in advance for your help.

 

Best regards
