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 50Ω 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.
