| Abstract | We designed a 7 mm band ambient temperature receiver in the laboratory. The receiver's radio frequency is 30-32 GHz, and the final output after the mixed frequency is 0.8-2.8 GHz signal of intermediate frequency. It is mainly used to carry out atmospheric opacity measurement in the 7 mm band (31.2 GHz), so as to proceed accurate amplitude calibration in the scientific observation of the 7 mm band. The receiver is mainly composed of the feed network and the post-stage microwave link. After the completion of development, the dynamic range of the receiver's intermediate frequency output spectrum is about 30 dB, and the power range is about -38 dBm. Subsequently, combined with the mechanical rotation platform of azimuth and elevation, the 7 mm band receiver can scan and measure in the range of 0-90° elevation, and the atmospheric opacity value of the corresponding band can be obtained through power acquisition and fitting calculation. |
