This capability can eliminate the need for In-phase and
Quadrature (I/Q) Digital-to-Analog Converters (DACs), quadrature
upconverters, and IF filters from the transmitter portion of the
radio system.
The device package and pinout for the 24-pin Quad Flat No-Lead
(QFN) package are shown in Figure 1. Figure 2 shows a functional
block diagram for the SKY72310.
