Rev. A | Page 15 of 19

APPLICATIONS INFORMATION

The evaluation board and typical application circuit are

optimized for low-side LO (upper sideband) performance

with the Mini-Circuit QCN-45+ RF 90° hybrid. Because the

I/Q mixers are double balanced, the ADMV1012 can support IF

frequencies from 3.5 GHz to low frequency.

TYPICAL APPLICATION CIRCUIT

The typical applications circuit is shown in Figure 34. The

application circuit shown has been replicated for the evaluation

board circuit.
