3.5 DAC3174 Output Performance for WCDMA and LTE
10 MHz of LTE signal is measured for Adjacent Channel Power Ratio (ACPR) performance, as shown in
Figure 9. The specification of this pattern is based on 3GPP LTE FDD E-TM1.1 and Quadrature Phase
Shift Keying (QPSK) of the modulation scheme. Measured ACPR shows –72.80 dB and –72.18 dB at
adjacent channel and –74.73 dB and –74.83 dB at alternate channel.
