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.
