The RF signal amplitude output of f HMC264LC3B is too low, which is 20dB lower than that of subharmonic.
you can see RF signal at 26.05GHz(-47.56dBm） when LO=13GHz (-4dBm), IF = 0.05GHz (-8.44dBm) .
But the amplitude of subharmonic(26GHz) is -20dBm.

The VDD is 4V and the current is 29ma, which meets the requirements.
I found that the amplitude of my IF signal is greater than 0, not alternating positive and negative. Is this the reason?
