研究目的
To report a 300 GHz source based on discrete Schottky diodes technology, featuring high power and high efficiency doublers without using power combining techniques.
研究成果
A discrete Schottky diodes-based 270-320 GHz source able to provide up to 35 mW without power combining techniques has been demonstrated, with state-of-the-art power handling capabilities and efficiencies.
研究不足
The input power to the D150 should not exceed 26 dBm for long periods to avoid efficiency loss. Standing waves between the D150 and D300 affect the conversion efficiency.
1：Experimental Design and Method Selection:
The design and fabrication of high power doublers based on a new discrete Schottky diode structure integrating a CVD diamond substrate.
2：Sample Selection and Data Sources:
Two discrete diodes placed in antiparallel balanced configuration for each doubler.
3：List of Experimental Equipment and Materials:
Signal generator, power supply, E-Band power meter, bias supply, X6 AFM, E-Band HPA, isolator, directional coupler, X2 ACST D150, X2 ACST D300, PM4 Power Meter.
4：Experimental Procedures and Operational Workflow:
Measurement setup characterization of the 270-320 GHz source, including power handling and conversion efficiency measurements.
5：Data Analysis Methods:
Comparison of output power and conversion efficiency with state-of-the-art technologies.
