Nonlinear Analysis of a Monolithic QWITT (Quantum Well Injection and Transit Time) Oscillator

Abstract

The small and large signal analysis of QWITT diode oscillators is presented. The small signal analysis determines the oscillation frequency of a power combining periodic structure. The large signal analysis, by the harmonic balance method, determines the power and efficiency of a single diode oscillator. These analyses show that the QWITT diode is good candidate for signal generation in the millimeter wave region. The theoretical results predict that powers of about 1 mW can be obtained at frequencies up to 600 GHz. At the end, experimental results are presented that confirm microwave operation of the QWITT device. The experiments have demonstrated powers of 300 micro W through the X-band.
