RF2174
3V DCS POWER AMPLIFIER
The RF2174 is a high power, high efficiency power amplifier module offer-
ing high performance in GSM or GPRS applications. The device is manu-
factured on an advanced GaAs HBT process, and has been designed for
use as the final RF amplifier in DCS1800/1900 hand-held digital cellular
equipment and other applications in the 1700MHz to 2000MHz band. On-
board power control provides over 65dB of control range with an analog
voltage input, and provides power down with a logic “low” for standby
operation. The device is self-contained with 50W input and the output can
be easily matched to obtain optimum power and efficiency characteristics.
The RF2174 can be used together with the RF2173 for dual-band opera-
tion. The device is packaged in an ultra-small plastic package, minimizing
the required board space.
