3.0 Theory of Operation
The SFC Upconverters have been designed to minimize the amount of hardware in the system while
maximizing performance. Spurious performance in the Upconverter is critical and in particular, LO
related spurious In-Band is nonexistent.
The SFC Upconverters are double conversion microwave Upconverters. The basic block diagram is
shown in Figure 3-1.
