Paper Abstract

The Submillimeter Array (SMA) is an 8-element mm/sub-mm interferometer on the summit of Maunakea, Hawaii that is operated jointly by the Smithsonian Astrophysical Observatory (SAO) and the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA). After nearly 13 years of operation, we are undertaking a major upgrade of the array's cryogenics, receivers and other systems that will enhance the science capabilities of the array and replace components reaching end-of-life. Here we describe the new receivers, containing dual-polarization, ultra-wideband SIS mixers operating at 230 and 345 GHz, the new ultra-wideband IF signal transport and correlator system, and the enhanced observing capabilities that will be enabled by this upgrade.
