“…In consideration of thermal dissipation, it is necessary to design a tripler with high efficiency to reduce requirement for high output power of the former source. In fact, the tripler based on unbalanced structure has been studied in our former research work, and the measured results show that the highest efficiency is 7.3% [8]. Compared with it, the performance of the 212 GHz tripler designed in this paper improves greatly.…”

Abstract-We introduce a 212 GHz LO source which could be used to drive sub-harmonic mixer in the radiometer front-end. It mainly includes a phase-locked dielectric resonator, a 71 GHz power source and a 212 GHz tripler. Actually, design of 212 GHz tripler is the key technology in the LO chain because the research on W band source is relatively mature. Based on our former research work, there is a great improvement in the design of 212 GHz tripler. At room temperature, the measured efficiency is more than 9% in 208 ∼ 218 GHz, and the maximum efficiency is about 14.5% at 215.5 GHz when being driven with 21.8 dBm of input power. Besides demand on the main technical specifications, the stability of each module is also extremely important since the front-end is designed to keep working for three months.

“…Compared with the doubler [8], its power capacity is smaller than this work, owing to the smaller number of anodes. Compared with the triplers in [12][13][14][15], the proposed tripler had higher output power and efficiency. Although a Because of the non-balanced circuit structure of the frequency multiplier, the efficiency is related to three variables: frequency, bias voltage, and input power.…”

“…It has been improved and developed since the work of Penfield [7]. Several multiplier topologies have been developed based on the inherent isolation characteristics of odd and even harmonics; for instance, the balanced frequency doubler [8][9][10][11], frequency tripler [12][13][14][15][16], frequency quadrupler [17,18], and frequency quintupler [19,20] structures.…”

The development of a millimeter-wave unbalanced frequency tripler based on the nonlinear characteristics of planar Schottky varactors is presented. The entire module is designed by hybrid integration. A frequency multiplier circuit model was established to reflect the influence of diode parameters and the impedance matching on the multiplier in different frequency bands. The effect of junction imbalance on the output power of the frequency multiplier was investigated and the multiplier was improved based on the basic design. The addition of a cut microstrip stub in the improved diode unit reduced the impact of a power imbalance on frequency multiplier performance. The characteristics of the multiplier circuit were analyzed by the full-wave electromagnetic simulation of the three-dimensional structure and the harmonic balance simulation of the circuit. Test results showed that the peak output power of the improved frequency tripler was 12.6 mW at 277 GHz with an input power of 200 mW, an effective 12% improvement over the basic design.

“…When the driving power was raised to 300 mW, the output power at 276 GHz reached a maximum of 15 mW. In 2020, Peter G. Hug-gard et al of ACST reported a 135-150 GHz tripler with low loss impedance matching based on waveguide resonator filter [97,98] . Impedance matching was achieved by adjusting the resonant frequency of the filter cavity, as shown in Fig.…”

The special position of terahertz wave in the electromagnetic spectrum makes it possess the characteristics of orientation, broadband, penetration and low energy, which promotes the extensive research of terahertz wave in the fields of communication, radar, imaging, sensing, security inspection and so on. The solid-state terahertz sources based on semiconductor devices have attracted extensive attention in the field of terahertz information technology due to their characteristics such as being able to work at room temperature, being small in size, being easy to integrate and having good frequency stability. Terahertz planar Schottky diode is a kind of low parasitic semiconductor device. Its high cutoff frequency makes it work well in the terahertz range. The frequency multiplier based on planar Schottky diode is an important part of terahertz solid state source. In this review, the development of Schottky diodes technology in recent years have been introduced, including the structures and preparation of Schottky diodes. In addition, the current situation and performance of different types of terahertz sources based on Schottky diodes are further introduced, and the future development trend is discussed.
