SE2520L
RangeCharger™ 2.4GHz Power Amplifier IC
Final
Applications
IEEE 802.11b DSSS Radios, Wireless LAN
2.4GHz Cordless Phones, ISM Radios
Bluetooth™ Wireless Technology
Product Description
The SE2520L is a power amplifier IC designed for the
2.4GHz ISM band and compliant with the IEEE
802.11b WLAN standard, providing up to +20dBm
typical output power at 3.3V with ACPR of –30dBc 1
st
nd
lobe and –50dBc 2 lobe, and requiring only 110mA.
For 2.4GHz cordless telephone applications, the
SE2520L produces +23dBm typical saturated output
power at 3.6V.
The SE2520L contains a linear analog control (0.1 to
1.6V) for controlling DC current and output power.
The SE2520L includes a digital enable control for
device on/off control. Ramping is 1 µsec typical.
This device is capable of operating at a duty cycle of
100 percent.
