Tenders are invited for Highly Efficient 20 W S-Band Amplifier for 5G-Connected Cars (Artes 4.0 Spl 5g/6g 7c.082) - Re_issue. The objective of the activity is to design, manufacture and test a highly efficient 20 W S-band Power Amplifier.Targeted Improvements:Efficiency higher than 70% - enabling technology for S-Band automotive applications.Description:Recent studies have shown the potential of satellite communications for 5G-connected cars. Although various frequency bands may be envisaged, the S-band can offer a simple systems architecture as well as a satisfactory link budget. However, due to the low gain of S-Band antennas, a dedicated high-power amplifier is necessary to close the link while offering a small footprint and high efficiency.This activity aims at developing such a power amplifier, which must be compatible with the constraints of the automotive market. A 20 W S-Band prototype, with 70% minimum efficiency, shall be designed, manufactured and tested.
