Product Description
The RF3146 is a high-power, high-efficiency power ampli-
fier module with integrated power control. The device is a
self-contained 7mmx7mmx0.9mm lead frame module
(LFM) with 50鈩?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 output. 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. On-board power con-
trol provides over 50dB of control range with an analog
voltage input; and, power down with a logic 鈥渓ow鈥?for
standby operation.
