Preliminary

RF2119

HIGH EFFICIENCY 2V POWER AMPLIFIER

Typical Applications

• Two-Way Pagers

• 3V AMPS/ETACS Cellular Handsets

• CDPD Portable Data Cards

• Personal Digital Cellular

• 915MHz ISM Band Equipment

• Spread-Spectrum Systems

Product Description

The RF2119 is a high-power, high-efficiency amplifier IC

targeting 2V to 4V handheld systems. The device is man-

ufactured on an advanced Gallium Arsenide Heterojunc-

tion Bipolar Transistor (HBT) process, and has been

designed for use as the final RF amplifier in hand-held

digital cellular equipment, spread spectrum systems, and

other applications in the 800MHz to 960MHz band. The

device is well suited for either CW or pulsed applications.

At 3V, the RF2119 can deliver 29.5dBm of linear output

power. The device is self-contained with 50Ω input and

the output can be easily matched to obtain optimum

power, efficiency, and linearity characteristics. The pack-

age is a PSSOP-16 with backside ground.
