WCDMA Applications
The TRF3702 is also optimized for WCDMA applications, where both adjacent-channel power ratio (ACPR) and
noise density are critically important. Figure 62 shows the noise performance of the modulator at a 60-MHz
offset over temperature. In addition, Figure 72 shows the 60-MHz offset noise measured at the output of the
TRF3702 versus WCDMA channel power. Using Texas Instruments' DAC568x series of high-performance
digital-to-analog converters in the configuration depicted in Figure 70 , state-of-the-art levels of ACPR have been
measured. In each case, test model 1 was used with 64 active channels as the baseband input to the TRF3702.
Figure 73 shows the performance attained for a single WCDMA carrier at 2.14 GHz, with a measured ACPR of
71.2 dBc for a channel power of –14 dBm. This unprecedented level of ACPR along with the low levels of noise
at 60-MHz offset makes the TRF3702 an optimum choice for such applications. Figure 74 shows the
single-carrier WCDMA ACPR performance versus channel power; it is important to note that even at high output
power levels, the TRF3702 maintains great linearity, offering 64 dBc of ACPR at an output-channel power of –8
dBm.
