320-420GHz Low-Noise Heterodyne Receiver Modules for the Submillimeter Array of Taiwan

摘要：

the development on the 320-420GHz SIS heterodyne receiver modules for the Submillimeter Array (SMA) of Taiwan is presented in this paper. This newly developed receiver band,along with the existing 250-354GHz SIS heterodyne receivers,provides dual-polarization observation capability over 320-354GHz,which cover important CO3-2 and HCN5-4 molecular emission lines from the celestial objects. The receiver configuration,including the optics,local oscillator and the receiver cryogenic section,will be described. The measured receiver DSB noise temperature is around 70-140K. The quasi-optical beam characteristics of the receiver module also measured at selected RF frequency to ensure good optics alignment.
