10. ALMA Band 6v2 Receiver Upgrade

Invited Talks

Invited Talk

We report on our proposal to develop an upgrade for the existing 211-275 GHz ALMA Band 6 receiver, referred to as “Band 6v2”, which complies with the strategies defined in the ALMA Development Roadmap to 2030 and with the recommendations of the ALMA Front-end & Digitizer Requirements Upgrade Working Group. The goal is to deliver an improved production-level receiver based on (i) a new Cold...

7. Development of a new wideband heterodyne receiver system (RF: 210–375 GHz, IF: 4–21 GHz) for the Osaka 1.85-mm mm-submm telescope

Invited Talks

Invited Talk

We report the development of a wideband receiver system using a corrugated horn covering 210–375 GHz (56% fractional bandwidth; Yamasaki et al. 2021, PASJ), wideband waveguide multiplexers (Masui et al. 2021, PASJ), and a wideband SIS-mixer with an IF (intermediate frequency) output of 4-21 GHz (Kojima et al. 2020, A&A). In the system, the RF signal from the horn is divided into two...
