I am using HMC493 in a cube-satellite receiver module. My question is what deflections in results should I expect if the input power(-25dBm) is lower than the recommended input power (-20dBm.)
Thank you in advance.
Here you go Timothy. These are for the HMC493 eval board, hope it helps.
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.
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.
