Abstract
In this work, a microwave down converter is proposed for nanosatellite electronic warfare applications. It provides high spurious suppression by exploiting a dual-conversion architecture and premium performance in terms of noise figure and linear dynamic range. The system design takes advantage of commercial off-the-shelf components, thus allowing for both fast and cost-effective prototyping, which are key requirements particularly concerning CubeSat systems. Since different military, commercial, radar and communication systems operate in the 2–18 GHz frequency band, the capability to integrate such kinds of receivers in CubeSats represents the new frontier of the electronic warfare systems. Moreover, due to the wide operating bandwidth, it can be successfully exploited as the receiver for different applications, e.g., satellite communication, radars, etc.
Highlights
Nowadays, military and defense departments pay particular attention to a wide variety of advanced technologies aimed at analyzing and manipulating the microwave frequency spectrum both for attack and defense purposes
The set of techniques and technologies employed to control and deny free access to the electromagnetic spectrum are commonly gathered under the name of electronic warfare (EW) [1,2,3]
Despite the great strides made by the researchers, the growing number of related scientific articles demonstrates that this is still a cutting-edge topic supported by a great scientific effort [4,5,6,7,8,9,10]
Summary
Military and defense departments pay particular attention to a wide variety of advanced technologies aimed at analyzing and manipulating the microwave frequency spectrum both for attack and defense purposes. CubeSat projects might be comp within a very short time compared to traditional satellite schedules They repre of commercial off-the-shelf (COTS) components, which are accessible by unigreat educational tools., e.g., for demonstrating technologies, novel techniques or s versity programs with limited budget. The down converter involves a dual-conversion architecture to provide a severe This task is addressed by first up-converting the received signal to a higher reduction of both the number and level of spurious signals in the band of interest. Another interesting feature of the proposed down converter concerns the possibility the operating frequencies of a great number of applications, e.g., satellite communica to be exploited for different applications. The operating frequencies of a great number of applications, e.g., satellite communication, radars, etc., where it can used as receiving stage [18,19,20,21,22,23]
