RF5111
3V DCS POWER AMPLIFIER
The RF5111 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 ampli-
fier in DCS1800/1900 handheld 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 50
Ω input and the
output can be easily matched to obtain optimum power and efficiency characteris-
tics. The RF5111 can be used together with the RF5110 for dual-band operation.
The device is packaged in an ultra-small plastic package, minimizing the required
board space.
