Description
The DSA-2000 is a large-scale radio telescope currently under development at Caltech, funded by Schmidt Sciences. Aligned with our funder's mission to “democratize access to astronomy resources by supporting global usage and open science,” we are committed not only to open data, but also to openly share reusable hardware and software designs as much as possible.
In this talk, I will present the analog signal path of the DSA-2000, focusing on the ambient-temperature low-noise amplifier (LNA) and the RF-over-fiber (RFoF) link design. Every part of the design is released under a strong copyleft license, ensuring broad accessibility and long-term reuse. This approach closely aligns with the CASPER vision of building a global ecosystem of open-source, modular hardware for radio astronomy.
