We analyzed output power limitations and structure dependencies for RTD THz oscillator with cylindrical cavity resonator. Dependences of the output power on resonant cavity dimensions show that output power generally increases with decreasing cavity size as well as with decreasing oscillation frequency. However, we found existence of low-frequency oscillation limit where output power rapidly decreases despite of increasing RTD mesa area. Analysis of numerical calculation results has shown that output power up to -34 dBm at 2.5 THz and up to -14 dBm at 1.5THz could be expected for single RTD oscillator considered in present study.
