Fraunhofer Institute for Applied Solid State Physics IAFLast modified:
Fraunhofer IAF and the Max Planck Institute for Radio Astronomy have provided 145 high-performance low-noise amplifiers for the ALMA radio telescope array in Chile’s Atacama Desert. The amplifiers are based on InGaAs mHEMT MMICs and are essential components of the high-frequency receivers for the wavelength range between 2.6 and 4.5 mm (frequency range: 67–116 GHz, known as Band 2). They will enable ALMA to perform more precise measurements of objects and galaxies in the universe in order to gain new information about the formation of stars, planets and life. The amplifiers delivered complete ALMA, which began scientific operations in 2011 and has been gradually expanded since then.
