ADF5355 gets too hot in use

Category: Hardware
Product Number: ADF5355

Hi,

        When using ADF5355 to generate a 8GHz frequency signal, the chip gets a little too hot, so the board gets hot too. And it can feel by the hand. However, the chip and the board can work fine to generate the 8GHz signal, which can be tested by the spectrum analyzer. Is this phenomenon normal? Or, is something wrong with my board? If there is somthing wrong, what could be the cause?

Thanks
