SE2528L

2.4 GHz Power Amplifier with Power Detector

Applications

Product Description

The SE2528L is a 2.4 GHz power amplifier 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.

DSSS 2.4 GHz WLAN (IEEE802.11b)

OFDM 2.4 GHz WLAN (IEEE802.11g)

Access Points, PCMCIA, PC cards

Features

The SE2528L is form, fit and function identical to

SiGe’s SE2525L. The SE2528L design can be

placed on SE2525L designs to provide higher output

power with only a few component changes.

Single 3.3 V Supply Operation

o 21 dBm, EVM = 3 %, 802.11g, OFDM 54

Mbps

o 24 dBm, ACPR < -32 dBc, 802.11b

The SE2528L also offers a high power mode by

operating at 5 V. This provides an extra 2 dB of

improved EVM performance.

Dual Supply Operation

o 23 dBm, EVM = 3 %, 802.11g, OFDM 54

Mbps

o 25 dBm, ACPR < -32 dBc, 802.11b

33 dB Gain

Pin for pin compatible to the SE2525L

The SE2528L includes a digital enable control for

device on/off control.

The device is pin for pin compatible to SiGe’s

SE2525L, allowing both devices to share the same

application board with only a few component changes

required. This provides users with both a high and

low power solution without changing the layout.

Selectable Power Detector Slope for use with

multiple chipsets (Negative and Positive)

Integrated power amplifier enable pin (V^EN)

Lead Free package, 16 pin 4 mm x 4 mm x 0.9

mm QFN

The SE2528L 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.
