AD9125 Image Rejection

Hello All,


One of my customers is designing RF transmitter by using AD9125 DAC.

His baseband frequency bandwidth is 26.6 to 45.6MHz.

Output RF signal should be 76MHz to 95MHz.

Clock frequency is 121.6MHz.

HB1 Control register is set as 10 (0.6 to 1.4 of 121.6MHz)

He tried to remove image band, 148.2MHz to 167.2MHz by HB2, however, ho couldn’t find good register setting.

Could you advise us how to remove the image frequency of 148.2MHz to 167.2MHz?


Thank you for your help.

Best Regards,
