ADF4159 RF input power range?

I have tried using HMC513 as a VCO driven by ADF4159 evaluation board.

 

On the datasheet, VCO output power is written as +5dBm~+11dBm.

 

ADF4159EVM has a 3dB attenuator so the RF power ADF4159 chip receives is +2dBm~8dBm.

 

RF input power is not clearly mentioned is the datasheet however the test condition RF input power range is -10dBm~0dBm

 

 

I am designing a circuit using both ICs, in this case will I need an attenuator that has attenuates more to satisfy the range of the test condition?

 

Can you tell me the safe range of RF input power of ADF4159 RFin pin?
