Typical Applications
鈥?3V Dual-Band GSM Handsets
鈥?Commercial and Consumer Systems
鈥?Portable Battery-Powered Equipment
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惟 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 鈥渓ow鈥?for standby
operation.
