A Calibrated Digital Sideband Separating Spectrometer for Radio Astronomy Applications
Ricardo Finger, Patricio Mena, Nicolas Reyes +2
Dual sideband (2SB) receivers are well suited for the spectral observation of complex astronomical signals over a wide frequency range. They are extensively used in radio astronomy…
A FPGA-based Fast Converging Digital Adaptive Filter for Real-time RFI Mitigation on Ground Based Radio Telescopes
R. Finger, F. Curotto, R. Fuentes +3
Radio Frequency Interference (RFI) is a growing concern in the radio astronomy community. Single-dish telescopes are particularly susceptible to RFI. Several methods have been deve…
The Atacama Large Millimeter/submillimeter Array (ALMA) Band-1 Receiver
Yau De Huang, Oscar Morata, Patrick Michel Koch +29
The Atacama Large Millimeter/submillimeter Array(ALMA) Band 1 receiver covers the 35-50 GHz frequency band. Development of prototype receivers, including the key components and sub…
Ultra-pure digital sideband separation at sub-millimeter wavelengths
R. Finger, F. P. Mena, A. Barishev +7
Deep spectral-line surveys in the mm and sub-mm range can detect thousands of lines per band uncovering the rich chemistry of molecular clouds, star forming regions and circumstell…
Microwave Loss Reduction in Cryogenically Cooled Conductors
R. Finger, A. R. Kerr
Measurements of microwave attenuation at room temperature and 4.2 K have been performed on some conductors commonly used in receiver input circuits. The reduction in loss on coolin…
