RF2173
3V GSM POWER AMPLIFIER
Package Style: QFN, 16-Pin, 4x4
The RF2173 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 GSM hand-held digital cellular equipment
and other applications in the 800MHz to 950MHz band. On-board power
control provides over 70dB 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
Ω input and the output can be easily
matched to obtain optimum power and efficiency characteristics. The
RF2173 can be used together with the RF2174 for dual-band operation.
The device is packaged in an ultra-small plastic package, minimizing the
required board space.
