Description

The AM52-0023 is a two stage power amplifier designed

for 802.11b and other 2.4 GHz applications.

This

product includes a detector and a T/R switch. Transmit

the AM52-0023 make it ideal for PC card applications.

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.
