Product Description

The RF5184 is a high-power, high-efficiency linear amplifier module specifically designed for 3V handheld systems. The device is manufactured on an advanced third generation GaAs HBT process, and was designed for use as the final RF amplifier in W-CDMA handheld digital cellular equipment, spread-spectrum systems, and other applications in the 824MHz to 849MHz band (Band 5) and 1850MHz to 1910MHz band (Band 2). The RF5184 has a digital control line for low power applications to lower quiescent current. The RF5184 is assembled in a 24-pin, 4mmx4mm, QFN package.
