drive input of the IQ modulator is generated by the TRF3761. The TRF3761 is a family of high performance,
highly integrated frequency synthesizers, optimized for wireless infrastructure applications. The TRF3761
includes an integrated VCO and integer-N PLL. Different members of the TRF3761 family can be chosen for
application specific VCO frequency ranges. In addition, the CDC7005 clocking solution can be used to clock the
DAC and other portions of the transmitter. A block diagram of the proposed architecture is shown in Figure 90
and Figure 91. For more details, contact Texas Instruments directly.
