Application Circuit
Bias-up Procedure
Vg set to -1.5 V
Vd set to +6 V
Adjust Vg more positive until quiescent Id is 650mA.
This will be ~ Vg = -0.55 V
Apply RF signal to RF Input
RF IN
J1
(Vg are either pins 7 and 8 or pins 23 and 24, Vd are either pins 10 and 11 or pins 20 and 21)
Vg = -0.55V
Typical
Vg and Vd can be biased from either side, and the non-biased side can be left open.
