Is my AD8302 fried?

I'm using the AD8302 for phase detection, with the circuit of the figure 4 on the datasheet.

I don't have the 1.8V in the Vref, C1 C4 C6 C5 C2 C8 = 100nF, R1 R2 = 51ohms, input 4MHz between 0 and -60dBm.

But every signal that I apply on the Input, the output becomes Vcc. Even if I variate the frequency or the amplitude level of my signals, the output has Vcc.What can I do? What's the matter with my circuit?
