RF5824
3.3V, DUAL-BAND WLAN
POWER AMPLIFIER MODULE
• IEEE802.11a/b/g and IEEE802.11n WLAN
Applications
• Single-Chip RF Power Amplifier Module
• 2.5GHz and 5GHz ISM Bands Applications
• Wireless LAN Systems
• Portable Battery-Powered Equipment
The RF5824 is a linear, medium-power, high-efficiency
dual-band power amplifier module designed specifically
for battery-operated WLAN applications such as PC
cards, mini-PCI and compact flash applications. It is also
designed to meet IEEE802.11a/b/g, IEEE802.11n, FCC,
and ETSI requirements for operation within the 2.4GHz to
2.5GHz and 4.90GHz to 5.85GHz bands. The device is
manufactured on an advanced InGaP GaAs Heterojunc-
tion Bipolar Transistor process, and has been designed
for use as the final RF amplifier in both the 2GHz and
5GHz WLAN and other spread-spectrum transmitters.
The
device
is
packaged
in
a
QFN,
24-pin,
4mmx4mmx0.9mm plastic package with back side
ground. The RF5824 operates from a single supply and
will be easily incorporated into WLAN and other designs
with minimal external components.
• 5GHz Integrated Output Match
• 11a Current 155mA Typical
• 11g Current 120mA Typical
• Gain 27dB Typical for 11a and 11g
• EVM 3.5% TYP for 11g and
3.5% TYP for 11a (@ POUT 11a/g=17dBm)
• Single Supply Voltage 2.8V to 4.0V
