When I Bias my GaN PA the Drain Current Increases to the Current Limit (No RF Applied) You may be experiencing DC bias oscillation. Long test cables (i.e. test setup) may increase DC bias lead inductance making the PA unstable. Adding a large capacitance (such as 47 uF in correct polarity) across the gate …	1	102	November 12, 2024
