GSM Applications
The TRF3703 is suited for GSM applications because of its high linearity and low noise level over the entire
recommended operating range. It also has excellent EVM performance, which makes it ideal for the stringent
GSM/EDGE applications.
WCDMA Applications
The TRF3703 is also optimized for WCDMA applications where both adjacent-channel power ratio (ACPR) and
noise density are critically important. Using Texas instruments’ DAC568X series of high-performance
digital-to-analog converters as depicted in
Figure 25
, excellent ACPR levels were measured with one-, two-, and
four-WCDMA carriers. See
