Product Description
The RF2705 is a low noise, multi-mode, quad-band direct
I/Q to RF modulator and PA driver designed for handset
applications where multiple modes of operation are
required. 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 90dB of power control range for
the W-CDMA mode and 40dB 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 2.7V to 3.3V operation, and is assembled in
a plastic, 24-pin, 4mmx4mm QFN.
