Abstract: Microwave I/Q up-converter is widely used in modern electronic systems to achieve single-sideband (SSB) up-conversion and vector modulation. However, due to the frequency-dependent mixer and ...

How does the new HackRF Pro perform in practical tests? We compare it with its predecessor, the HackRF One, analyze improvements in RF characteristics, noise behavior, and dynamics – and demonstrate ...

The Committee on Earth Science and Applications from Space (CESAS) provides an independent, authoritative forum for identifying and discussing Earth system science research requiring data from space ...

When astronauts set foot on Mars, it will be one of humanity’s greatest milestones. These first steps will be the result of decades of research, engineering, and imagination coming together, marking ...
