Hi, once I use HMC836 as a Local oscillator output 3.6GHz. The circuit schematic is designed following the evaluation board. There is no problem in the previous two years, and the output power is about 2dBm. After a few years, they are generally reduced to -5dBm. The output power requirements can't reached, and the overall circuit failure appears.
Do you have received any feedback in this regard. Do you have any repair measures besides replacing a new HMC836 chip? Thank you!
