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 sec.
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.
