Product Description
The SE2523BU 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.
The SE2523BU includes a digital enable control for
device on/off control.
The SE2523BU 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.
