Recommended Bias-Up Procedure
NOTE: To protect the device, this MMHEMT MMIC will be biased differently than typical
NOTE: Be sure proper ESD protection is in place
A. If biasing Drain through Vd DC port
B. If Biasing Drain through Bias Tee and RF port
PHEMT devices
1. Leave Vg at 0V
2. Increase Vd to 1 V
3. Adjust Vg to reach 50 mA
4. Increase Vd to 4.5 V
5. Repeat steps 3 and 4 until correct bias is reached (i.e. Vd = 4.5 V, Id = 50mA)
6. To Bias-down device, turn Vg to 0V and decrease Vd to 0V
1. Leave Vg at 0V
2. Increase Vd to 1 V
3. Adjust Vg to reach 50 mA
4. Increase Vd to 2 V
5. Repeat steps 3 and 4 until correct bias is reached (i.e. Vd = 2 V, Id = 50mA)
6. To Bias-down device, turn Vg to 0V and decrease Vd to 0V
