Note:

2. The gain for the unmatched device in 50 ohm system is shown as the trace in black color. For a tuned circuit for a

particular frequency, it is expected that actual gain will be higher, up to the maximum stable gain. The maximum stable

gain is shown in the dashed red line.

3. The impedance plots are shown from 0.5 – 6 GHz, with markers placed at 0.5 – 6.0 GHz in 0.5 GHz increments.
