Notes:

The gain for the unmatched device in 50 ohm system is shown as the trace in blue color. For a tuned circuit for a particular frequency, it

is expected that actual gain will be higher, as high as the maximum stable gain. The maximum stable gain is shown in the red line. The

impedance plots are shown from 10 – 6000 MHz, with markers placed at 0.5 – 6.0 GHz in 0.5 GHz increments.
