Bias Instruction for RFHA3960 Evaluation Board
 ESD Sensitive Material. Please use proper ESD precautions when handling devices of evaluation board.
 Evaluation board requires additional external fan cooling.
 Connect all supplies before powering up the evaluation board.
1. Connect RF cables at RFIN and RFOUT.
2. Connect ground to the ground supply terminal, and ensure that both the VG and VD grounds are also connected to this
ground terminal.
3. Apply -8V to VGate.
4. Apply 28/48V to VDrain.
5. Increase V_G until drain current reaches desired 50mA bias point.
6. Turn on RF input.
