W-cdMa operation

The HMC1197LP7FE is suitable for W-CDMA operation. Figure 51 shows the adjacent and alternate

channel power ratios for the HMC1197LP7FE at an LO frequency of 2140 MHz. The HMC1197LP7FE

is able to deliver about −72 dBc ACPR and −77 dBc AltCPR at an output power of −10 dBm. ACPR and

AltCPR performances of the HMC1197LP7FE can be improved by adjusting the DC common-mode level

on the I and Q baseband inputs.
