Product Description
IEEE 802.16 WiMAX Systems
The RF5603 is a linear power amplifier IC designed specifically for WiMAX
medium power applications. The device is manufactured on an advanced
InGaP Heterojunction Bipolar Transistor (HBT) process, and has been
designed for use as the final RF amplifier in 802.16e transmitters. The
device is provided in a 3mmx3mmx0.45mm, 16-pin, leadless chip carrier
with a backside ground. The RF5603 is designed to maintain linearity over
a wide range of conditions and power outputs.
