RF5355

3.3V, 5GHz LINEAR POWER AMPLIFIER

The RF5355 is a linear, medium-power, high-efficiency power amplifier IC

designed specifically for battery-powered WiFi applications such as PC

cards, mini PCI, and compact flash applications. It is also designed to

meet IEEE802.11a, IEEE802.11n, IEEE802.16e (4.9GHz to 5.850GHz

only) WiMax, FCC, and ETSI requirements for operation in the 4.9GHz to

5.850GHz band. The device is manufactured on an advanced InGap GaAs

Heterojunction Bipolar Transistor process, and has been designed for use

as the final RF amplifier in 5GHz WiFi and other spread-spectrum trans-

mitters. The device is provided in a QFN, 8-pin, 2.2mmx2.2mmx0.45mm,

leadless chip carrier with backside ground. The RF5355 operates from a

single supply and will be easily incorporated into WiFi and other designs

with minimal external components.
