Evaluation Board Turn-On Sequence
Recommended turn-on sequence:
1) Connect common ground terminal to the Ground (GND) pin on the board.
2) Connect voltmeter to VDET (P-Sense).
3) Apply positive supply voltage (3.3 V) to pin VCC (Collector voltage).
4) Apply positive bias voltage (2.9 V) to pin VPC (Power Control voltage).
5) At this point, you should expect to observe the following positive currents flowing into the pins:
6) Apply input RF power to SMA connector pin RFIN. Current for pin VCC will vary depending on the input drive level.
7) Vary positive voltage VPC from +2.9 V to +0 V to shut down the amplifier or alter the power level. Shut down current flow
Recommended turn-off sequence:
Use reverse order described in the turn-on sequence above.
Note:
1. Turn on sequence is not critical and it is not necessary to sequence power supplies in actual system level design.
