ADRF6516 LPF with VGA SIngle ended input configuration

I would like to drive the ADRF6516 with 1MHz Single ended input, whether it is possible to drive in single ended configuration

  • Hi Satish,

    All of the characterization was done while being drivnig differentially.  I'm researching your question right now and will get back to you in a day or so.

  • Hi Satish,

    You can drive the ADRF6516 single ended if you AC ground (via a large capacitor to ground) the unused input,  but degraded distortion wll occur when comparing the same input amplitude and frequency to the differential case.  A 0.5 Vpp single ended signal is the max recommended to still get decent distortion numbers (about 55-58 dBc).  Also, distorion will degrade as you increase frequency.
