We investigate a non‐Foster element implemented with a radio‐frequency operational amplifier theoretically and experimentally, showing that its full‐range frequency response exhibits an inverted Lorentzian resonance, and thus a high‐frequency non‐Foster response can be observed on the right side of the resonance region. This can be used to overcome the technical difficulty in achieving high‐frequency non‐Foster elements.
