I am using ADL5513 for RF Pulse detection from 500MHz to 2.0GHz operation(Broadband) without any input filter. I am using single ended operation as suggested in the datasheet. I found some oscillations around 9.16MHz getting generated at the detector output, when i switch off the input signal, and the same is appearing for my Pulse RF Input. But when my signal is continuous then output voltage is very clean. I just wanna know whether somebody also had the same problem or is it because of our layout or supply issues?
