Consideration on modeling of the operation frequency of an InP HEMT/MMIC oscillator illuminated by a 1.5 μm laser

摘要

In this report, experimental data and their investigation by a simulator of an oscillation frequency shift in MMIC oscillator illuminated by a 1.5 μm laser were described. Illumination with the small gate-source bias, the operating frequency was shifted higher compared to the self-oscillating one. Using a microwave circuit simulator, computed operating frequencies with tuning the capacitance value in the FET equivalent circuit model were observed using the harmonic balance analysis.
