RF3140 is a high-power, high-efficiency power amplifier module with integrated power control for use in 3V quad-band GSM handsets. It incorporates a power control function and has 50Ω input and output terminals, making it possible to drive the module directly from the DAC output. The device is designed for use as the final RF amplifier 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. The on-board power control function provides over 50dB of control range with an analog voltage input; and, power does not ramp down when the DAC output is turned off.
The RF3140 is a high-power, high-efficiency power amplifier module designed for use as the final RF amplifier in GSM850, EGSM900, DCS, and PCS handheld digital cellular equipment. It features an integrated power control function that eliminates the need for external directional couplers or detector diodes, allowing the module to be driven directly from a DAC output.
