SE2425U

RangeCharger^TM2.4 GHz Bluetooth Power Amplifier IC

Preliminary Information

Applications

Product Description

Bluetooth^tmwireless technology (Class 1)

USB dongles, PCMCIA, flash cards, Access Points

Enhanced data rate

A monolithic, high-efficiency, silicon-germanium power

amplifier IC, the SE2425U is designed for 2.4 GHz

wireless applications, including Bluetooth^TMClass 1

basic rate and enhanced data rate applications. It

delivers +25 dBm output power in standard rate GFSK

mode and +19.5 dBm output power in enhanced rate

8DPSK.

Features

Integrated input and inter-stage match

+25 dBm GFSK Output Power

The SE2425U provides a digital mode control input for

boosting the linear performance for enhanced data rate

applications.

+19.5 dBm 8DPSK Output Power

Low current: 110 mA typical @ P_OUT= +20 dBm

Ultra low quiescent current: 28 mA

Digital Enable for direct interface to standard

CMOS processors

The SE2425U operates at 3.3 V DC with a peak

efficiency of 43 % in basic rate and 21 % in enhanced

rate mode. The internal bias management allows the

part to only draw 28 mA in Class 2 output power levels.

Mode-control for easy switching between standard

and EDR modes

Gain: 29 dB

Output match integrates the high Q inductors to reduce

component count and bill of materials. It uses two

external capacitors to allow for varying loads, such as

switches and filters, in different applications.

3.3 V single supply operation

Ordering Information

The silicon/silicon-germanium structure of the

SE2425U, 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.
