Product Description

The SE2550BL is a 2.4 GHz front end module

designed for use in the 2.4 GHz ISM band for portable

wireless LAN applications.

The device offers high

efficiency at the required output powers to ensure

longer battery life for cellphone, PDA and other

portable applications.

The SE2550BL is highly integrated, allowing for a

smaller footprint and simple design.

The device

includes a power amplifier, digital enable control for

device on/off control, T/R Switch, harmonic filter and

50 ohm matching on all I/O. With the digital enable

control, the device can be directly connected to a

CMOS baseband or transceiver.

The SE2550BL 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.
