Product Description
The RF3110 is a high-power, high-efficiency power ampli-
fier module with integrated power control. The device is
self-contained with 50Ω input and output terminals. The
power control function is also incorporated, eliminating
the need for directional couplers, detector diodes, power
control ASICs and other power control circuitry; this
allows the module to be driven directly from the DAC out-
put. The device is designed for use as the final RF ampli-
fier in GSM/DCS and PCS handheld digital cellular
equipment and other applications in the 880MHz to
915MHz, 1710MHz to 1785MHz and 1850MHz to
1910MHz bands. On-board power control provides over
35dB of control range with an analog voltage input; and,
power down with a logic “low” for standby operation.
