In the defense industry there is a demonstrated trend towards providing guidance in missile and gun launched munitions down to as small as 20mm. Couple this with a trend requiring systems to utilize much higher frequencies and the RF and Microwave industry is uniquely challenged with engineering a solution that supports moving up the spectrum and unprecedented size reduction along with extreme environmental exposure. This interactive presentation will provide detail and best practices surrounding the design challenges of this evolving field. Examples are a guided artillery shell that experiences accelerations greater that 30,000 time the force of gravity (9.8m/s2), leave a barrel with rotation exceeding 3000 revolutions per minute and a highly variable power source. The talk will start with an overview of these new munitions, the missions and system requirements. We will then discuss the design requirements based on a semi-active gun launched guided munitions. After looking at the signal chain requirements, the presenters will show methods for packaging RF/Microwave designs into cylindrical packages / System in Package including interfaces to both processing systems and antenna. Next the extreme g-force requirements for a pyrotechnic launched munition will be discuss along with design considerations for surviving the event and rapid turn on and stabilization. The presentations concludes with the storage requirements for munitions and design considerations for a 20 year shelf life with minimum maintenance. The session will conclude with a 15 minute discussion including systems and electrical engineers who are building the first generation of guided munitions.
