TraPoS (Transistor Power Supply)

TraPoS (Transistor Power Supply) is a programmable 8-channel power supply for FET based low noise amplifiers, which controls the drain voltage of a transistor, while maintaining a target drain current flowing through it, letting the transistor stay at its ideal operating voltage and current condition. This is accomplished by controlling the transistor’s gate voltage while measuring its drain current, and compensating the voltage drop at the drain. This device’s components allow a sufficient amount of output drain current for most, if not all, of the currently available Low Noise Amplifiers.

The Millimeter-wave laboratory (MWL) designs, builds and tests receivers for use in radioastronomy with a focus on academic activities and technological research. We are a heterogeneous group of astronomers, engineers, technicians and students, with a joint experience that covers from decametric to sub-millimeter techniques. The Laboratory begins with the transfer of the equipment from the Maipú Radio Observatory on the year 2000 and the relocation/upgrade of the MINI (1.2m mm-wave radio telescope) from Cerro Tololo to Cerro Calan. Today, we are involved in several projects related to mm-wave receivers in collaboration with a number of groups abroad. Together with the Department of Electrical Engineering (DIE), which runs a photonics laboratory, we have formed the Astronomical Instrumentation Group.
