RF2119
HIGH EFFICIENCY 2V POWER AMPLIFIER
•Two-Way Pagers
• 915MHz ISM Band Equipment
• Spread-Spectrum Systems
• 3V AMPS/ETACS Cellular Handsets
• CDPDPortableDataCards
• Personal Digital Cellular
The RF2119 is a high-power, high-efficiency amplifier IC
targeting 2V to 4 V 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 3 V, the RF2119 can deliver 29.5dBm of linear output
power. The device is self-contained with 50
Ω 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.
• Single 2V to 5V Supply
• 30dBm Output Power at 2.5V
• 30dB Small Signal Gain
• 53% Efficiency
• On-board Power Down Mode
• 800MHz to 960MHz Operation
