2.4 GHz Power Amplifier with Power Detector

Preliminary

Applications

Product Description

The SE2523BU is

a 2.4 GHz power amplifier

DSSS 2.4 GHz WLAN (IEEE802.11b)

designed for use in the 2.4 GHz ISM band for wireless

LAN applications. The device incorporates two

selectable power detectors for closed loop monitoring

of the output power.

OFDM 2.4 GHz WLAN (IEEE802.11g)

Portable and Battery WLAN Applications

Access Points, PCMCIA, PC cards

The SE2523BU includes a digital enable control for

device on/off control.

Features

Single 3.3 V Supply Operation

The SE2523BU temperature compensated power

detector has two selectable power detectors slopes,

positive and negative. This allows easy use with

multiple chipsets. The detector is also highly immune

to mismatch at its output with less than 1.5 dB of

variation with a 2:1 mismatch.

18.5 dBm, EVM = 3 %, 802.11g, OFDM 54 Mbps

23 dBm, ACPR < -32 dBc, 802.11b

32 dB Gain

Selectable Power Detector Slope for use with

multiple chipsets (Negative and Positive)

Integrated power amplifier enable pin (V^EN)

Lead Free and RoHS Compliant
