Connections Quadrature Demodulation

Two AD831 mixers may have their RF inputs connected in parallel

and have their LO inputs driven in phase quadrature (Figure 11)

to provide demodulated in-phase (I) and quadrature (Q) outputs.

The mixers’ inputs may be connected in parallel and a single

termination resistor used if the mixers are located in close prox-

imity on the PC board.
