The RF5146 is a high-power, high-efficiency power amplifier module with integrated power control that provides over 50 dB of control range. The device is a self-contained 7 mm x 7 mm x 0.9 mm lead frame module (LFM) with 50 ? input and output terminals. 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 824 MHz to 849 MHz, 880 MHz to 915 MHz, 1710 MHz to 1785 MHz and 1850 MHz to 1910 MHz bands. With the integration of a VRAMP limiting circuit, the RF5146 can regulate the VRAMP voltage to ensure minimum switching transients. The VRAMP limiter function is fully integrated into the CMOS controller and requires no additional inputs from the user
