Iam using the EV1HMC6300BG46 and EV1HMC6301BG46 Eval-boards together with a self build custom board.
I am wondering why the HMC6300 is not having a greater RF output power than -26,xxdBm . It seems as even if I increase the different VGA gains there is a kind of saturation at this output power, so with different higher gain settings the power is not increasing. My LO is from a very clean arbitrary function generator and suits the specs in power output.
what could be the cause of this behaviour?
