Product Description
The RF2172 is a medium-power high efficiency amplifier
IC targeting 3.6V handheld systems. The device is manu-
factured on an advanced Gallium Arsenide Heterojunc-
tion Bipolar Transistor (HBT) process, and has been
designed for use as the final RF amplifier in 2.45GHz
Bluetooth applications and frequency hopping/direct
sequence spread-spectrum cordless telephones or other
applications in the 902MHz to 928MHz ISM band. The
device is packaged in a compact 4mmx4mm LCC. The
device features analog gain control to optimize transmit
power while maximizing battery life in portable equipment
requiring up to 100mW transmit power at the antenna
port.
