A negative resistance Indium Phosphide MMIC subcircuit element is presented that employs a Double-Heterojunction Bipolar Transistor in Common Emitter configuration with series feedback. The fabricated MMIC exhibits negative resistance up to 231GHz, this being the highest known frequency at which negative resistance has been measured for a transistor in the Common Emitter configuration. The design methodology is based on a simple equation that accurately predicts the value of series feedback reactance required to generate negative resistance in a transistor. The negative resistance subcircuit described has potential application in a reflection amplifier or negative resistance oscillator, when combined with a suitable resonator.
