4. Recommended Operating Procedure on the Evaluation Board
Power Up:
Dual supply operation, (for Single Supply operation, please contact ANADIGICS).
A. Begin by setting all power supplies to zero volts.
B. Make sure that the input RF power is turned off.
C. Apply – 4.0 V to VSS (Pin 14)
D. Apply + 4.8 V to VDB VD1,VD2 and VD3.
E. Set VC to 0.0 Volts for AMPS/GSM operation or Set VC to 3.0 Volts for DCS or PCS operation.
F. Apply + 7 dBm of RF power to pin 5 for AMPS/GSM operation, or apply + 9 Volts to pin 10 for
DCS/PCS operation.
G. Apply a positive pulse train for GSM,DCS or PCS operation to VREF (pin 3). Adjust pulse
amplitude for desired output power.
H. For AMPS operation apply a positive DC voltage to the VREF (pin 3) and adjust value for
desired output power. (0 V< VREF < 3.6V).
Power Down:
To power down the device follow the above procedure in reverse order.
