RF3854 Low Noise, Multi-Mode, Quad-Band, Quadrature Modulator and PA Driver
The RF3854 is a low noise, multi-mode, quad-band direct I/Q to RF modulator and PA driver solution designed for digital modulation applications ranging from 800 MHz to 2000 MHz. Frequency doublers, dividers and LO buffers are included to support a variety of LO generation options. Dynamic power control is supported through a single analog input giving 90 dB of power control range for the W-CDMA mode and 40 dB of power control in the other two modes. Three sets of RF outputs are provided: high band and low band low noise EDGE/GMSK outputs, as well as one wideband W-CDMA output. The device is designed for 2.7 V to 3.3 V operation, and is assembled in a plastic, 24-pin, 4 mm x 4 mm QFN.
