4. Recommended Operating Procedure on the Evaluation Board
Power Up
A.
Begin by setting all power supplies to zero volts.
B. Make sure that the input RF power is turned off.
C. Turn on V
SS
(Pin 8) to (-) 4.0V
D. Check the voltage @ V
G1A
(Pin 1), V
G1B
(PIN 14), V
G2B
(PIN 17) and V
G2A
(PIN 28) to see if it is between
-3.8V and -3V. If voltage is not negative, check the pin alignment.
E. Turn on V
