Product Description
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 transmitters. 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.
