Hi,

 

I have build a circuit for AD8302. The gain measurement seems ok but the phase measurement is not working. I also input 2 signals, which have 1GHz and 1.001GHz. But I have not seen a triangle wave at the oscilloscope. I use circuit just like the one in datasheet in reflectometer part.

 

I wonder where could I do wrong in the circuit. Could you please help me?
