Evaluation Board Turn-On Sequence
Recommended turn-on sequence:
1) Connect common ground terminal to the Ground (GND)
pin on the board.
2) Apply low voltage 0.0 to +1.0 V to pin V
3) Apply positive supply voltage VC1 (= 3.3V) to pin VC1
(first stage collector).
4) Apply positive supply voltage VC2 (= 3.3V) to pin VC2
(second stage collector).
5) Apply positive bias voltage VM12 (= 3.3V) to pin VM12
(bias networks).
6) At this point, you should expect to observe the following
positive currents flowing into the pins:

7) Apply input RF power to SMA connector pin RFIN.
Currents in pins VC1 and VC2 will vary depending on the
input drive level.
8) Vary positive voltage V
+2.4V to shut down the amplifier or alter the power level.
Shut down current flow into the pins:
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
