Recommended Operating Procedure on the Evaluation Board
Power Up
A. Begin by setting all power supplies to 0.0 Volts, and input power to 0 dBm.
B. Make sure that the RF input power is turned off.
C. Turn on VSS (Pin 3) to (-) 3V.
D. Turn VDS1 (Pin 1), VDS2 (Pin 9), VDS3 (Pins 11, 12, 13 and 14) and VDDC (Pin 4) which are tied together on the
fixture, and set to +3.5V and set VREF (Pin 3) for IDQ of 140 mA
E. Turn RF on and adjust input power to get POUT = 28.5 dBm.
Power Down
To power down the device follow the above procedure in reverse order.
