AD831 as an Image Reject Mixer

Mindy
on Jan 24, 2020

Hi,

I am thinking of using the AD831 in an Image Reject Mixer application.

Is there an application circuit available from ADI that I can use to achieve this please.

The Mixer is to be used to convert an RFin of 156MHz - 162MHz to an IF of 30MHz.

Many Thanks

Mindy

    Hi,

    Sorry we don't have a specific application note for image reject mixer. Basically you need two of these mixers and feed them with I and Q signals. The differential output should be summed in that case. There should be a lot of resources available online showing how to use differential mixer for image rejection.

    Thanks.
