PE4140 in Mixer Applications
The PE4140 is inherently a broadband device, capable of operating as a broadband mixer by
adding a few external parts. At a minimum, three transformers are required to create a
double-balanced mixer. This is shown in Figure 4 below. The PC board provides solder
footprints to accept this circuit without any modifications. Figure 5 shows a schematic with
compnent values for a PCS down Converter.
