Titolo: | Compact Dual-Polarization Cryogenic Receiver Module for the 75-116 GHz band | Autori: | NAVARRINI, Alessandro VALENTE, Giuseppe Serres, Patrice Schaefer, Franck Thome, Fabian Garnier, Olivier |
Data pubblicazione: | 2018 | Titolo del volume in cui è pubblicato il poster: | 2018 International Conference on Electromagnetics in Advanced Applications (ICEAA) | Da pagina:: | 479 | Abstract: | We describe the design of a highly integrated cryogenic receiver module based on an “active” waveguide Orthomode Transducer (OMT) for dual-polarization radio astronomy observations across 75-116 GHz (3-mm band). The receiver module consists of passive and active sections incorporated in three mechanical blocks arranged in a very compact assembly. The module has external dimensions of 43×25×35 mm3; it includes a square waveguide input (size 2.54×2.54 mm2) and two standard WR10 waveguide outputs (size 1.27×2.54 mm2) parallel to the input waveguide, suitable for integration in a focal plane array. The passive section of the receiver module employs a broadband backward-coupler waveguide OMT while the active section consists of two ultra-low noise MMIC (Monolithic Microwave Integrated Circuit) amplifiers in cascade, delivering a total gain of ≈45 dB for each of the polarization channels. The “active OMT” receiver will be cryogenically cooled at the physical temperature of ≈15 K. It is expected to provide state-of-the-art performance with noise in the range 25 to 50 K across 75-116 GHz. The module incorporates a DC power supply board along with discrete capacitors, resistors, and a DC bias connector for biasing the MMIC amplifiers. | Titolo del convegno: | 2018 International Conference on Electromagnetics in Advanced Applications (ICEAA) | Luogo del convegno: | Cartagena des Indias, COLOMBIA | Periodo del convegno: | 10-14 September, 2018 | URI: | http://hdl.handle.net/20.500.12386/28218 | URL: | https://ieeexplore.ieee.org/document/8520415 | ISBN: | 978-1-5386-6762-0 | DOI: | 10.1109/ICEAA.2018.8520415 | Fulltext: | open |
