Abstract

This letter presents a 135–150 GHz high-efficiency and -power Schottky diode-based tripler integrated with low-loss waveguide filtering matching network. The active diode monolithic microwave integrated circuit (MMIC) is matched with two waveguide filters based on coupling matrix theory for a two-port network with complex impedance terminations. The filters and the active diode MMIC are integrated via the microstrip-to-waveguide transition, allowing a compact design on the relatively higher loss MMIC. In addition, an integrated on-chip capacitor is implemented to isolate dc and RF paths. The measurement shows that with 150–200 mW input power, the maximum conversion efficiency reaches 30.5% and the maximum output power is 47 mW. All filtering poles can be observed in measurements and the return loss achieves 10–15 dB within the passband. Good agreements between measurements and simulations demonstrate the validity of the design approach.

带滤波匹配网络的135 - 150ghz大功率三倍频器

这封信提出了一个135–150千兆赫高效率和功率肖特基二极管与低损耗波导滤波匹配网络集成的三倍频器。基于耦合矩阵理论，将有源二极管单片微波集成电路（MMIC）与两个波导滤波器相匹配，用于具有复杂阻抗终端的双端口网络。滤波器和有源二极管MMIC通过微带到波导的转换而集成，从而允许在相对较高损耗的MMIC上进行紧凑设计。此外，集成片上电容器被实现为隔离直流和射频路径。测量表明，在150–200 mW的输入功率下，最大转换效率达到30.5%，最大输出功率为47 mW。测量中可以观察到所有滤波极点，通带内的回波损耗达到10–15 dB。测量和模拟之间的良好一致性证明了设计方法的有效性。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
