“…They are designed by appropriately biasing and loading oscillator circuits to optimize conversion gain . Two prototypes of self‐oscillating mixers were proposed: the first one, a self‐oscillating mixer based on a feedback oscillator that used a rectangular SIW cavity placed in the feedback path of a field‐effect transistor (FET)‐based amplifier circuit , and the other, an X‐band active antenna self‐oscillating down‐converter SIW mixer , with IF frequency of 3.15 GHz for conversion gain in at least 600 MHz bandwidth around the IF frequency. As in case of oscillators, there are several areas where SIW technology can be explored for mixer design.…”

The use of substrate integrated waveguides (SIW) for microwave and millimeter wave integrated components has increased dramatically over the last decade. They mimic the performance of conventional metallic waveguides and they are fabricated using printed circuit boards using the top and bottom metallization with two rows of vias forming the side walls. This creates a low profile, compact, and light weight alternative to conventional metallic waveguides, and they allow a direct interconnection with printed circuit boards and active components. This article reviews the fundamental theory, documents the research that has been performed over the past decade, and summarizes progress up to the recent state-of-the-art including novel SIW structures for passive circuits and antennas as well as new applications for reconfigurable and printed circuits using SIW technology.

“…An optimization of the via layout reduces the need for shielding apparatuses, thus simplifying the mechanics and reducing mass, volume and hardware costs. In last years, many studies related to filters [6], mixers [7]- [9], oscillators [10], [11], low-noise [12]- [15] and power amplifiers [16]- [20] in SIW technology were published. The application of this technology to front-ends, however, is scarcely documented.…”

This paper proposes a Ka-band receiver front-end for future CubeSats Low-Earth Orbit (LEO) to Geostationary (GEO) inter-satellite links. The receiver is able to support very high data rates (up to 100 Mbit/s) in Quadrature Phase-Shift Keying (QPSK) when in the line of sight of a GEO satellite that is equipped with a steerable 70-cm antenna and transmitting a 25-W signal. The originality of the proposed approach is twofold. First we will demonstrate the receiver feasibility based on a class of miniaturized and low-cost microwave integrated circuits, currently available on the market. In particular, our receiver is based on a novel combination of integrated Low-Noise Amplifiers (LNA) with an image rejection filter, the latter exploiting the Substrate Integrated Waveguide (SIW) technology. An optimization of the via placement proved to be able to reduce the need for shielding apparatuses, thus simplifying the mechanics and reducing mass, volume and hardware costs. Secondly, we will propose a noise injection circuit capable of measuring and calibrating the receiver gain, also during in-orbit operation. Self testing capabilities are particularly relevant for CubeSats because the usage of commercial components poses serious reliability issues.
