MGA-83563 Test Circuit
Typical s-parameters are shown below for
various inductor values (L). Those marked
“Sim” are simulated and those marked
“Meas” are measured using an ICM (Inter-
continental Microwave) xture. Figure 17
shows the available gain for each L value.
The user should rst select the L value for
the application frequency before design-
ing an input, output, or power matching
structure
.
