Xinjiang 110 m radio telescope (QiTai Telescope, QTT) will play an important role in the field of fundamental science, such as gravitational wave detection, black holes, star formation and galaxy origin, and also be applied to deep space explorations, for example, Lunar Exploration Program and Exploration of Mars and Venus. However, many ultra-wideband, multi-beam receivers will be applied for various science goals of QTT, and we will be faced with numerous significant challenges. In this paper, we have presented the technical progress of ultra-wideband receiver for large aperture telescope, including the ultra-wideband feeds/Ortho-Mode Transducer (OMT), Low Noise Amplifier (LNA) and multi-beam receiver. Meanwhile, key techniques and challenges were analyzed for receiver research and fabrication. Based on the science requirements and the technique development, we have proposed the preliminary scheme for QTT receiver system, and discussed about the feed forms, primary devices research and key coming difficulties and challenges. radio astronomy, ultra-wideband, receiver technology, large aperture telescope

This paper proposes 2GHz ~ 8GHz UWB LNA with totem pole technique for low noise figure. The LNA was designed using 0.15 µm GaAs pHMET process. The designed LNA was simulated in ADS tool. The LNA exhibits a S(2,1) of 33.4~29.7 dB, minimum noise figure is 1.383~1.391 dB, reverse isolation was better than 40 dB in entire band. The LNA draws 32 mA. Resistive feedback technique was used for wideband matching and low noise figure. General TermsRFIC,

This article presents a Ku‐band Low Noise Amplifier (LNA) Monolithic Microwave Integrated Circuit (MMIC) and RF front‐end module for space applications. LNA MMIC was developed with utilizing 0.07 μm GaAs m‐HEMT process. Noise Figure (NF) and gain results of LNA module were measured as 1.3 and 43 dB, respectively and OIP3 was measured as +20 dBm at the ambient temperature. The LNA module was tested in the temperature range between −25°C and 75°C and small signal gain and NF variation were less than 3 and 0.8 dB, respectively. This article describes the MMIC LNA design, mechanical chassis design, WR75 waveguide‐to‐microstrip design, and measurement results of the LNA front‐end module.
