TGA4539-SM
Ka-Band 1 Watt Power Amplifier
Application Circuit
Bias-up Procedure
Turn Vg to -1.5 V
Turn Vd to +6 V
Adjust Vg more positive until quiescent Id is 420 mA.
This will be ~ Vg = -0.59 V typical
Apply RF signal
Vd must be biased from both side (pins 8, 9, 17, 18)
Vg can be biased from either side (pin 7 or pin 19)
- 7 of 14 -
Bias-down Procedure
Turn off RF signal
Reduce Vg to -1.5V. Ensure Id ~ 0 mA
Turn Vd to 0 V
Turn Vg to 0 V
