Remarkable
Power Up
1) Begin by setting all power supplies to zero volts, and input power to –30 dBm.
2) Make sure that the RF input power is turned off.
3) Turn on V
G1
(Pin 8) and V
G2
(Pin 14 and 15) to (–) 3.3 V.
4) Adjust V
D1
(Pin 10) and V
D2
(Pin 2, 3 and 4) to V
DS1
= V
DS2
= 3.5 V, respectively.
5) Adjust V
G1
and V
G2
to I
DSQ1
= 80 mA and I
DSQ2
= 200 mA, respectively.
6) Turn RF on and adjust input power (Pin = 7 dBm) to get Pout = 31.5 dBm.
Power down
To power down the device follow the above procedure in reverse order.
