Evaluation Board Turn-On Sequence
1
Recommended turn-on sequence:
1) Connect common ground terminal to the Ground (GND) pin
on the board.
2) Connect voltmeter to pin DT1 (VDET, voltage detector).
3) Apply positive supply voltage VC1 (=3.3 V) to pin VC1 (first
stage collector).
4) Apply positive supply voltage VC2 (=3.3 V) to pin VC2 (sec-
ond stage collector).
5) Apply positive supply voltage VC3 (=3.3 V) to pin VC3 (third
stage collector).
6) Apply positive bias voltage VM123 (=2.9 V) to pin VM123
(bias networks).
7) At this point, you should expect to observe the following posi-
tive currents flowing into the pins:
8) Apply input RF power to SMA connector pin RFIN. Currents
in pins VC1, VC2 and VC3 will vary depending on the input drive
level.
9) Vary positive voltage on pin VM123 from +2.9 V to +0 V to
shut down the amplifier or alter the power level. Shut down cur-
rent 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 sup-
