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 VGEN (Pin 13) to + 4.8 V
D. Check the voltage @ VSSIN (pin 5) to see if it is between - 4.8 V and – 3V, if voltage is
not, check the pin alignment.
E. Turn on VD1 (Pin 27), VD2 (Pin 16), VD3 (Pins 19 and 24) and VDB (Pin 4) which are tied
together on the fixture, and set to +6.0 V. Little drain current should be flowing at this
time (IDD< 5 mA).
F. Turn RF on and adjust input power to 5 dBm.
G. Turn VREF on. Adjust VREF to desired output power (< = 33.0 dBm).
Power Down
To power down the device follow the above procedure in reverse order .
