SE2527L

2.4 GHz Power Amplifier with Power Detector

Preliminary Information

Applications

Product Description

The SE2527L is a 2.4 GHz power amplifier designed

for use in the 2.4 GHz ISM band for wireless LAN

DSSS 2.4 GHz WLAN (IEEE802.11b)

OFDM 2.4 GHz WLAN (IEEE802.11g)

Access Points, PCMCIA, PC cards

applications. The device incorporates

power

detector for closed loop monitoring of the output

power.

Features

The SE2527L also offers a high power mode by

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

improved EVM performance.

Single 3.3 V Supply Operation

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

Mbps

The SE2527L includes a digital enable control for

device on/off control.

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

Dual Supply Operation

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

The device is pin for pin compatible to SiGe’s

SE2524L, 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.

Mbps

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

32 dB Gain

Pin for pin compatible to the SE2525L

Integrated temperature compensated power

detector

Integrated power amplifier enable pin (V^EN)

Lead Free and RoHS compliant

The SE2527L temperature compensated power

detector is highly immune to mismatch at its output

with less than 1.5 dB of variation with a 2:1 mismatch.
