A problem about ADL5350 passive mixer

I used the mixer ADL5350 to realize the difference frequency of the RF 100MHz and the LO 99MHz,  the RF and LO signals are all from the frequency synthesis with the output of PECL level, whice are squire signals and not the sinewaves. And I just used the recommend circuit in the datasheet. But I got nothing on the IF port. meanwhile,the signal on RF port is very strange which is  like the phenomenon  of  u=Ldi/dt. I had tried to change the filter network ,and this still could not work.   So how to solve it?
