• GSM850/EGSM900/DCS/PCS Products
• GPRS Class 12 Compatible
• Power StarTM Module
The RF3140 is a high-power, high-efficiency power ampli-
fier module with integrated power control. The device is
self-contained with 50
Ω 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 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.
• Complete Power Control Solution
• Single 3.0V to 5.5V Supply Voltage
• +35dBm GSM Output Power at 3.5V
• +33dBm DCS/PCS Output Power at 3.5V
• 60% GSM and 55% DCS/PCS
