RF5603

3.0V TO 5.0V, 3.3GHz TO 3.8GHz

LINEAR POWER AMPLIFIER

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.
