ADF4351 EVM low output power at low frequency

Hi,

 

I want to know if it is normal behaviour for you eval board to show about 130mV when I terminate the RfoutA+ and RfoutA- with a 50 ohms load, at a 70MHz frequency, while probing directly on the board?  I was expecting a 5dBm output power. Basically I need a 300mVpp swing to feed a clock input and i want to know if I need a amplifier. Thanks!
