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 50input 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.
