“…A proven way to improve the power handling of multipliers is power‐combining multiplying structures using split and combined waveguide networks. Multiplying power‐combing structure can be realized by using Y‐junction waveguides, hybrid couplers, waveguide dividers or, spatial dividers and placing them in a single waveguide . An in‐phase power‐combined tripler at 265–300 GHz with 5%–15% efficiency was proposed in Ref.…”

In this article, a novel 110–170 GHz balanced tripler is presented with high‐efficiency and high‐power handling. To implement the proposed tripler, a multilayer multiplier scheme is introduced with two‐layer parallel metal fin line transitions and four planar diodes based on spatial power combining concept. Fin line transitions are used to constitute two‐layer ridge waveguides. They divide the input signal to diodes with the same amplitude and combine the third harmonic with output waveguide. The proposed tripler eliminates the dielectric loss and has good balancing characteristic, which enable the tripler to get fabulous performances such as high power handling, high‐efficiency, excellent spectral purity, and so on. The measured results shown that the tripler achieves an efficiency of 5.7%–7.8% with 147–208 mW input power and its power handling is more than 0.5W.

“…This enables comprehensive insight into the high-frequency parasitic effects caused by the device geometry which exerts unneglectable influences on circuit performance [6,7], and thus results in effective design of high-performance circuits in THz band. By taking into account of numerical analysis results from the 3D EM modeling of the diode geometry, better agreement between the predictions and measurement results was achieved in [4,8] compared with the cases in [9, 10] which were based on conventional equivalent circuit modelling of the device geometry. Furthermore, one of the core issues in the SHM's design is the synthesis of the embedding network for the Schottky diodes.…”

This paper presents the design of a low noise Schottky-diode 190-240 GHz subharmonic mixer (SHM). The embedding impedance condition for the diodes to yield optimum circuit performance is primarily determined. It is achieved using the computer-aided design (CAD) load-pull techniques by taking into account the high-frequency parasitic effects caused by the diode chip geometry. By knowing this condition, the design procedure of the mixer circuitry is expedited. The design effectiveness of the proposed methodology is experimentally validated by the good agreement between the design predictions and the measured results of the mixer performance. Y-factor measurements show that the mixer exhibits the double side band (DSB) noise temperature lower than 1500 K and DSB conversion loss less than 10 dB over the 190-240 GHz frequency range, with the DSB noise temperature and conversion loss at 220 GHz of 800 K and 7 dB respectively.
