Product Description
The RF3146 is a high-power, high-efficiency power amplifier module with integrated
power control. The device is a self-contained 7mmx7mmx0.9mm lead frame mod-
ule (LFM) 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 output. The device is designed for use as the final RF ampli-
fier in GSM850, EGSM900, DCS and PCS handheld digital cellular equipment and
other applications in the 824MHz to 849MHz, 880MHz to 915MHz, 1710MHz to
1785MHz and 1850MHz to 1910MHz bands. On-board power control provides
over 50dB of control range with an analog voltage input; and, power down with a
logic “low” for standby operation.
The RF3146 is part of the POLARIS
