Figure 89. TRF3761 Layout
Much in the same way as described above, the TRF3761 is an ideal synthesizer to use in implementing a
complete high performance RF transmitter chain such as the TSW3000 and TSW3003 Demonstration kits. Using
a complete suite of high performance Texas Instruments components, a state-of-the-art transmitter can be
implemented featuring excellent performance. Texas Instruments offers ideal solutions for the digital-to-analog
conversion portion of transmitter as well as the analog and RF components needed to complete the transmitter.
The baseband digital data is converted to I and Q signals through the dual DAC5687, which features a 16-bit
interpolating dual digital-to-analog converter (DAC). The device incorporates a digital modulator, independent
differential offset control, and I/Q amplitude control. The device is typically used in baseband mode or in low IF
mode in conjunction with an analog quadrature modulator. The DAC5687, after filtering, feeds a TRF3703, which
is a direct, upconversion IQ modulator. This device accepts a differential input voltage quadrature signal at
baseband or low IF frequencies and outputs a modulated RF signal based on the LO drive frequency. The LO
