Product Description
The RF2173 is a high power, high efficiency power ampli-
fier 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 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 opera-
tion. The device is self-contained with 50鈩?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, min-
imizing the required board space.
