“…During inorbit operation, the RF cable components outside the cabin are affected by multiple high-and lowtemperature changes in the space. Its VSWR (voltage standing wave ratio) will increase, the insertion loss will increase, and the performance of the transmission path will deteriorate [4] , which will affect the normal operation of the satellite transceiver link and even lead to the failure of the whole system. As shown above, taking a certain type of aerospace RF cable assembly as an example, during its development process, there was a deterioration in the microwave performance of the product after temperature cycling tests.…”

The aerospace RF cable assembly is an important component for the propagation of space communication signals, which can achieve impedance matching and energy transmission of microwave signal transmission paths. In addition to the requirements for a wide frequency range, low insertion loss, and low standing wave as required for conventional RF cable components, it must also possess high reliability, spatial temperature resistance, vacuum high-power transmission, and other spatial adaptability capabilities. This article primarily discusses the damage to the insulation materials of cable components under space-limit temperatures and its impact on the performance of the cable components. The problem of deterioration and even failure of the performance of aerospace RF cable components in high and low-temperature alternating environments in space has been addressed through the adoption of corresponding measures.

“…Te rapid improvement of microwave communications technologies has continuously increased in signal frequency [1][2][3][4]. However, 2.92 mm coaxial millimeter-wave connectors cannot support signal frequencies greater than 46 GHz, necessitating the use of millimeter-wave connectors that can support frequencies of 65 GHz and above.…”

It is difficult to simultaneously ensure the radio frequency (RF) performance and mechanical strength of 65 GHz millimeter-wave connectors. To address this, satisfaction-based multiobjective method for connector design optimization is proposed. An optimization model is developed for the structural dimensions of 65 GHz millimeter-wave connectors to minimize the voltage standing wave ratio, insertion loss, and deflection and maximum stress of the center conductor. The proposed optimization model concurrently satisfies the design requirements in terms of characteristic impedance, transmission frequency, and dielectric withstanding voltage. The model is optimized by innovatively using the multiobjective chaotic optimization algorithm in microwave finite-element simulations. The resulting optimal structure satisfies all performance requirements, thereby proving the rationality and feasibility of the proposed method. Moreover, this study establishes a novel design for other microwave devices to solve the problem of multiple performance index restrictions.
