Analysis of microwave amplifiers on resonance-tunnel diodes
Incoming article date: 22.09.2017The characteristics of amplifiers on resonant-tunnel diodes (RTDs) are analyzed using the method of approximation to them and operating at frequencies close to resonant. It was revealed that the nonlinear and resonant properties of the amplifier on the RTD are related and determined from each other; the nonlinearity of the current-voltage characteristics of the RTD imparts a resonant curve to the form that usually occurs in the case of nonlinear reactivity. It is established that for large signals it is necessary to take into account the frequency dependence, which will complicate the course of the resonance curves. In this question, the most complete equivalent RTD scheme without simplifications.
