Product Description

The SE2527L is a 2.4 GHz power amplifier designed

for use in the 2.4 GHz ISM band for wireless LAN

applications.

The

device

incorporates

a

power

detector for closed loop monitoring of the output

power.

The SE2527L also offers a high power mode by

operating at 5 V.

This provides an extra 2 dB of

improved EVM performance.

The SE2527L includes a digital enable control for

device on/off control.

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.

The

SE2527L

temperature

power

detector is highly immune to mismatch at its output

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