The amplifier requires a matching network at the input for proper operation. The amplifier is intrinsically well matched at the output and ideally should “look” into 50 . Any deviation from this can affect the linearity IP3 performance for the device. 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. The impedance plots are shown from 250 – 1000 MHz, with markers placed at 0.25 – 1.0 GHz in 0.25 GHz increments.
