A New Structure 0.3 THz Frequency Multiplier

In this paper, a new type of transition structure is used to design and simulate a 330GHz passive frequency multiplier. The input and output ports of the frequency multiplier are on the same horizontal line, the loss is smaller than that of the conventional transition structure, and the volume is reduced by one-third. one. When inputting 100mw, the frequency multiplier outputs 9mw near the center frequency, the peak output efficiency reaches 9%, and the output power is greater than 3mw in the frequency range of 315-335GHz. It has excellent performance and can be used as the local oscillator source of the post-stage system, or applied to other terahertz systems.
