Bias quiescent currents held constant.
VSWR 10:1, all phase angles. No
degradation in output power before &
after test.
0<Pout<44.8 dBm CW, 3:1 VSWR
Theta jc is for output device. Verified
with IR scan. Note 2.
These DC quiescent currents are typical
of the levels that produce optimum
linearity for CDMA protocol.
Ratio of sense FET current, relative to RF
FET current. Ratios are: Stg 1: 33:1;
Stg 2: 58:1 Gates of sense & RF FETs
are DC connected. Measured with no RF
signal present.

Mil STD 883E, Method 3015 for Human
Body Model and for Machine Model.
