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.
Features
High linear output power for IEEE802.11b,
st
nd
+20dBm, ACPR 1 lobe –30dBc, 2 lobe –50dBc
Low current consumption: 110mA at 3.3V
High saturated output power for cordless
telephone applications: +23dBm, 140mA at 3.6V
Single supply voltage: 2.7 to 3.6V
Wide Temperature range: -40 to +85°C

Description
Controls the RF output power level and DC current of the power amplifier. An analog
control signal between 0.1V and 1.6V varies the PA output power between Min. and
Max. values.
Power Amplifier Enable pin. A digital control signal with logic high (power up) and logic
low (power down) is used to turn the device on and off.
Power amplifier RF input, external input matching network with DC blocking is required.
Bias supply voltage.
Stage 1 collector supply voltage, an external inter-stage matching network is required.
PA Output and Stage2 collector supply voltage, external output matching network with
DC blocking is required.

Absolute Maximum Ratings
These are stress ratings only. Exposure to stresses beyond these maximum ratings may cause permanent damage
to, or affect the reliability of the device. Avoid operating the device outside the recommended operating conditions
defined below. This device is ESD sensitive with an ESD rating of < 600V. Handling and assembly of this device
should be at ESD protected workstations.
