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.
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.
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.
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.
