Abstract: | We have developed a 3 mm band receiver for SRAO. The receiver employs an Nb-based SIS junction in the mixer and operates at 85–115 GHz with single polarization. The receiver noise temperature is 40–50 K in DSB. It is equipped with an MPI-type filter for single-side band observations. We present the design, construction, and test results for individual components of the receiver optics, heterodyne system, and cryogenics. The receiver has been installed on the 6 m SRAO telescope and tested toward astronomical sources. The beam-measurement experiment suggests that the edge taper is smaller than the designed 12 dB. |
