Product Description
The RF3166 is a high-power, high-efficiency power ampli-
fier module with integrated power control that provides
over 50dB of control range. The device is a self-contained
6mmx6mm module with 50  input and output terminals.
The device is designed for use as the final RF amplifier in
GSM850, EGSM900, DCS and PCS handheld digital cel-
lular equipment and other applications in the 824MHz to
849MHz, 880MHz to 915MHz, 1710MHz to 1785MHz
and 1850MHz to 1910MHz bands. The RF3166 incorpo-
tracking circuit, which monitors
rates RFMD’s latest V
BATT
battery voltage and prevents the power control loop from
reaching saturation. The V  tracking circuit eliminates
BATT
the need to monitor battery voltage, thereby minimizing
switching transients. The RF3166 requires no external
routing or external components, simplifying layout and
reducing board space.
