DAC5682Z output filter

Hello,

Fig 49 on page 48 of the datasheet (SLLS853E- Revised August 2012) shows a bandpass filter after the transformer for suppress the DAC Nyquist zone images and other spurious signals.

Do you have any reference design or design guide for such filter, our intent is using 1GSPS for fo = 400 MHz.

Best regards,

Mark
