Impedance matching method in high-power RTD THz oscillator integrated with rectangular-cavity resonator

We propose an impedance matching method to increase the output power of novel resonant tunneling diode (RTD) terahertz oscillator. An equivalent circuit model and analysis method for the oscillation characteristics were established. A matching point for output power was found by changing MIM capacitor, and the simulation results show that high output power, like 5 mw, is possible to be achieved at around 1 THz.
