The objective of AMSTAR+ is to develop the technology required for the construction of large format (two dimensional) focal plane heterodyne arrays (FPAs) operating from 80 GHz (3.8 mm) to 2 THz (0.15 mm). The aims of the project include the:
- development of a prototype W-band heterodyne array module using metamorphic HEMT technology,
- exploration of practical solutions for the construction of large 2-D heterodyne FPAs,
- investigation of integrated pixel and photonic LO solutions for a large mm-wave FPA,
- extension of low noise heterodyne FPA technology into the 1-2 THz frequency band.
The 3-year programme will target the technical developments needed for the construction of large format (two dimensional) focal plane heterodyne arrays (FPAs) operating at up to 2 THz. The focus will lie in the development of heterodyne detection devices. Prototype array modules will demonstrate the adequacy of these devices for the construction of large FPAs for single-dish telescopes, as well as interferometers. Optimization of local oscillator (LO) distribution and integration of components will lead to more effective arrays.
