PA2423U

RangeCharger^TM2.4 GHz Bluetooth^tmPower Amplifier IC

Preliminary

Applications

Product Description

A monolithic, high-efficiency, silicon-germanium power

amplifier IC, the PA2423U is designed for 2.4 GHz

wireless applications, including Bluetooth^TMClass1 and

2.4 GHz cordless telephone applications. It delivers

+22.5 dBm output power making it capable of

overcoming insertion losses of up to 2.5 dB between

amplifier output and antenna input.

Bluetooth^tmwireless technology (Class 1)

USB dongles

PCMCIA, flash cards

Access points

2.4 GHz cordless telephone

Features

The PA2423U provides a digital control input for

controlling power up and power down modes of

operation.

+22.5 dBm Output Power

Low current 108 mA typical @ P_OUT= +20 dBm

CMOS Enable Interface

The PA2423U operates at 3.3 V DC. At typical output

power level (+22.5 dBm), the current consumption is

135 mA.

Power-control and power-down modes

3.3 V single supply operation

Thin, lead-free 6 pin QFN package

The silicon/silicon-germanium structure of the

PA2423U, and its exposed die-pad package, soldered

to the system PCB, provide high thermal conductivity

and a subsequently low junction temperature. This

device is capable of operating at a duty cycle of 100

percent. The device is pin for pin compatible to the

PA2423L.
