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 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 amplifier in

EGSM900 and DCS handheld digital cellular equipment

and other applications in the 880MHz to 915MHz and

1710MHz to 1785MHz bands. On-board power control

provides over 50dB of control range with an analog volt-

age input; and, power down with a logic “low” for standby

operation.
