Product Description
The RF2174 is a high power, high efficiency power amplifier module offering high performance in GSM or GPRS applications. The device is manufactured 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. Onboard 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 50: 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 operation. The device is packaged in an ultra-small plastic package, minimizing
the required board space.
