for 802.11b

Features

• WLAN and Bluetooth Applications

• Meets 802.11b Spectral Mask Requirements at +20

dBm PA Output Power

• Integrated SPDT Switch

• Integrated Detector

• Downset Leadframe for Excellent Heat Dissipation

• High Power, Low Power, Shutdown Modes

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
specifications are given at the antenna port and include
the switch insertion loss. The small size and height of
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.

Handling Procedures

Please observe the following precautions to avoid
damage to the AM52-0023:

Static Sensitivity

Gallium arsenide integrated circuits are ESD
sensitive and can be damaged by static electricity.
Use proper ESD precautions when handling these
devices.
