I am noticing some very strange behavior when biasing the HMC8410. Starting from a gate voltage of -2V, I turn a potentiometer and slowly increase the gate voltage while monitoring the drain quiescent current (RF input is not applied). The drain quiescent current increases from 1 to 10 mA, and then suddenly spikes to 100 mA. Attempting to then decrease the gate voltage (and correspondingly the drain current), the current decreases smoothly to ~85 mA before suddenly dropping back to 1 mA. Any insight into this strange behavior would be appreciated!
