An input >= -20dBm minimum input power (i.e. power level at the input pin) is the specification that guarantees the HMC493 will behave like /4 divider. If input signal is smaller then -20dBm the input may not recognize that an input signal is present and as…
Here you go Timothy. These are for the HMC493 eval board, hope it helps.

Hi Eric,
In the past we have found that 8.25k was the appropriate value to prevent self oscillation without RF input for the HMC492, HMC493, and HMC494.

Dir Sir,
I would like to know the equivalent hours of HMC764LP6CE & HMC783LP6CE. I cnn't find the information in the attached Reliability Report. How can I calculate that value?
Best regards,
Akira
Hi,
It sounds like the divider is self oscillating when the input is removed. There is an app note on this phenomenon at the link below. The appropriate value to prevent self oscillation without RF input is 8.25k for the HMC492, HMC493, and HMC494.
