“…The test results showed a maximum output power of 70 mW and a maximum efficiency of 30%. In 2014, J. V. Siles et al from JPL laboratory in the United States, introduced a tripler of power synthesis on chip of 105-120 GHz and 550 GHz [118] . The 105-120 GHz frequency tripler was divided into two channels after input transition, and each subunit circuit was composed of six diodes.…”

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.

“…Eight LO chains consisting of a combination of amplifier and multiplier stages multiply the frequency of a low noise W-band synthesizer signal to the required target LO frequency. 27,28 The LO signal is divided by waveguide power divider into nine outputs to match the mixer arrays, similar to the 16 beam example shown in Fig. 5.…”

“…29 HERO requires extremely efficient multipliers as we have only allocated 2 W of DC power to each amplifier chain. The design of amplifier multiplier chains up to 2.7 THz with sufficient power to pump an array of mixers is difficult, but the prototype chains already exist for single-pixel applications, e.g., Mehdi et al 27 for an overview, VDI 28 with 5 μW at 2.7 THz. An alternative approach for the LO source is the Quantum Cascade Laser (QCL).…”

The Heterodyne Receiver for Origins (HERO) is the first detailed study of a heterodyne focal plane array receiver for space applications. HERO gives the Origins Space Telescope the capability to observe at very high spectral resolution (R ¼ 10 7 ) over an unprecedentedly large far-infrared (FIR) wavelengths range (111 to 617 μm) with high sensitivity, with simultaneous dual polarization and dual-frequency band operation. The design is based on prior successful heterodyne receivers, such as Heterodyne Instrument for the Far-Infrared /Herschel, but surpasses it by one to two orders of magnitude by exploiting the latest technological developments. Innovative components are used to keep the required satellite resources low and thus allowing for the first time a convincing design of a large format heterodyne array receiver for space. HERO on Origins is a unique tool to explore the FIR universe and extends the enormous potential of submillimeter astronomical spectroscopy into new areas of astronomical research. © The Authors.Published by SPIE under a Creative Commons Attribution 4.0 Unported License.
