Hi,

My customer want to design various Up/Down converter block using BiCMOS Mixers(ex.HMC686, HMC687.....).

According to the application circuit of these mixers, balun is recommended for single-ended type in IF stage as below.

But, the customer want to use single-ended without balun in IF stage.

Is it possible to use only positive line in IF stage without balun?

Could you please provide an application note for the solution that do not use balun ?

Thanks.
