Power Amplifier with T/R Switch for 802.11b Preliminary Release The AM52-0023 has three operating modes; High Power, Low Power, and Shutdown. The High Power Mode has both the first and second PA stages biased on and is achieved by setting both Vctrl1 and Vctrl2 to +3 volts. The Low Power Mode has the first PA stage on and the second PA stage off and is achieved by setting Vctrl1 to +3 volts and Vctrl2 to 0 volts. The Shutdown Mode is achieved by setting both Vctrl1 and Vctrl2 to 0 volts.
