摘要：

The ALMA 2030 Development Roadmap defines the long-term scientific objectives and serves as a guide for the development activity for the upgrade of hardware, software, and analysis tools in order to enhance the future observing capabilities of ALMA. A working group was established to define a set of consistent system level technical goals in order to guide the ongoing and future ALMA technical development effort. The working group has prepared an updated set of technical goals for Front-end and Digitizer products to enable the scientific needs as stipulated in the ALMA 2030 Development Roadmap. This manuscript describes the working group's considerations of system trade-offs and feasibility studies and presents tentative specifications arrived at for some of the key technical requirement goals.
