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
lobe and –50dBc 2

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.
