Description
The SKY42068 is an integrated, high-dynamic range low-noise
receiver down converter. It includes a double-balanced active
mixer, Local Oscillator (LO) amplifiers, and dual LO inputs
selected by an external switch interface. The LO switch function is
managed using an externally controlled CMOS-compatible
interface.
The 20-pin Quad Flat No-Lead (QFN) device package and pinout
are shown in Figure 1. Figure 2 shows a functional block diagram
for the SKY42068.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances) compliant packaging.
