“…Due to the low power level of an individual solid-state device, it is necessary to combine power from multiple devices to obtain the desired power level. Some power-combining technologies based on finline and substrate integrated waveguide (SIW) have been proposed [1,2,3,4,5,6]. In [1,2,3], the power combiners based on finline and double-layer finline have been proposed.…”

“…These combining structures can be fabricated using the standard printed circuit board (PCB) process and easily assembled into three-dimension waveguide structure. SIW has been a popular transmission in recent years [4,5,6,7], which can offer a compact and costeffective solution for integrating microwave circuits. Some combiners based on SIW have been proposed [4,5].…”

A novel wideband four-way divider/combiner based on substrate integrated waveguide (SIW) and double-layer finline is presented. This divider/combiner designed at 29-40 GHz is mainly composed of the doublelayer finline transition from waveguide to SIW and the double-microstrip transition from SIW to microstrip. These transitions feature the function of power divider/combiner, as well as the function of transition. The measured power-combining efficiency of this circuit at 35.6 GHz is 86%, and the combining efficiency is higher than 75% at 29-40 GHz.

“…In fact, a considerable number of SIW based devices designed using commercial codes, like HFSS (Ansys HFSS), have been presented over the years. Filters [2-4, 23, 24], power dividers [5][6][7], antennas [8,9,25] and other devices have been successfully designed and realized. However, more effective analysis methods can be devised implementing techniques that, even less general than the one used in commercial codes, are more efficient in terms of both CPU time and occupied memory.…”

Abstract-In this paper, a full-wave analysis technique of lossy substrate integrated waveguides, based on the dyadic Green's function of the parallel plate waveguide, is presented. The field inside the waveguide is expressed in terms of cylindrical vector wave-functions and the finite conductivity of the top and of the bottom plates, and of the metallic vias are taken into account. Losses into the dielectric substrate are also included. Coaxial ports are considered as sources and self and mutual admittances are evaluated. Cases of practical structure taken from literature are presented showing a very good agreement with the most used commercial software.

This paper presents the integration and channel characterization of a highly integrated dual-band digital beamforming space-borne synthetic aperture radar (SAR) receiver. The proposed SAR sensor is a low-cost, lightweight, low-power consumption, and dual-band (X/Ka) dual-polarized module ready for the next-generation space-borne SAR missions. In previous works, by the authors, the design and experimental characterization of each sub-system was already presented and discussed. This work expands upon the previous characterization by providing an exhaustive experimental assessment of the fully integrated system. As it will be shown, the proposed tests were used to validate all the instrument channels in a set-up where the SAR sensor was illuminated by an external source minim the ground reflected waves. Test results demonstrate how the system channels are properly operating allowing the reception of the input signals and their processing in the digital domain. The possibility to easily implement a calibration procedure has also been validated to equalize, in the digital domain, the unavoidable amplitude differences between the different channels.
