NuWaves Engineering, an international Radio Frequency (RF) solutions company, has been selected to present a technical abstract at the 1st Annual International Space Station (ISS) Research and Development Conference on June 28th in Denver, Colorado. NuWaves’ abstract focuses on Small Business Innovation Research (SBIR) work which concentrates on High Efficiency Switching RF Power Amplifiers intended for Earth Radar Observation in the L, S and X bands.

Traditional PA classes based on limited conduction angle topologies (i.e., Classes AB, B, and C) are unable to achieve the better than 50 percent efficiency required by the solicitation over a large bandwidth. Therefore, NuWaves’ work focuses on the more efficient breed of switching power amplifiers. In particular, the focus of the investigation is the Class F and Inverse Class F PAs incorporating new techniques to operate broadband on multiple radar bands. NuWaves target for efficiency is in the 60 to 80 percent percent range which will significantly reduce battery size and cooling requirements in space for the technologies High Efficiency Switching Power amplifiers for Earth Radar Observation Systems (HESPEROS) by NASA, as part of the government agency’s efforts to pursue smaller and more affordable spacecraft.

“The Small Business Innovation Research (SBIR) program not only meets specific Federal research and development needs,” said Jeff Wells, President and CEO of NuWaves Engineering, “it also allows small businesses the opportunity to display their entrepreneurial spirit by competing to stimulate high-tech innovation.”

NuWaves Engineering is a premier supplier of Radio Frequency (RF) and embedded systems products and solutions for DoD, non-DoD government, and industrial customers. An RF engineering powerhouse, NuWaves offers a wide range of engineering design services focused on wireless communications, as well as a complete line of commercially available module-levelproducts, such as wideband RF upconverters and downconverters, high-efficiency miniature solid state power amplifiers, high intercept low noise amplifiers, miniature RF filters, and fiber optic RF distribution modules.
