Evaluation Board Turn-On Sequence
1
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
L
.
3) Apply positive supply voltage VC1 (= 5.0V) to pin VC1 (first
stage collector).
4) Apply positive supply voltage VC2 (= 5.0V) 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 posi-
tive 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
shut down the amplifier or alter the power level. Shut down cur-
rent flow into the pins:
L
on pin VREG from +0.5V to +2.4V to
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 sup-
plies in actual system level design.
