The 3.5GHz RF OUT of our Eval_HMC836LP6CE is only -5.5dBm measured by Signal Analyzers(RSA5100B). This power is far below 6dBm in the HMC836 datasheet. I hope engineers can help us to solve the problem. Thank you very much.
The eval board software installation includes a register configuration file for the HMC836. Use the GUI to load this file -- this will setup the correct configuration for the VCO sub-system. I've attached this file.
