Product Description
The SE2522BL is a 2.4GHz power amplifier. The device
is designed for use in the 2.4GHz ISM band for wireless
LAN and cordless telephone applications. It incorporates
a power detector for closed loop monitoring of output
power.
For wireless LAN applications, the device meets the
requirements of IEEE802.11b and delivers
approximately +23dBm @ ACPR = -30dBc. In
IEEE802.11g applications the PA delivers approximately
16dBm.
For cordless telephone applications, the SE2522BL
delivers up to +25dBm saturated output power at 3.3V.
The SE2522BL includes a linear analog control (0.1 to
1.6V) for minimizing DC current consumption and
maximizing PAE.
The SE2522BL contains a digital enable for device on/off
control, ramping is typical 1 µsec.
The SE2522BL contains an integrated power detector
with an input power range of 15dB, and an accuracy of
± 1.0dB. An accurate automatic level control function can
easily be implemented using this detector circuit.
