| Abstract: | This paper introduces a new temperature stabilization circuit for the 3mm oscillator on the 13.7m radio telescope, which is located in Delingha, Qinhai. The operating mode of the new circuit is different from the original switch mode. The 3mm oscillator with this temperature stabilization circuit shows good stability. The output power variation of the overall receiver system has been improved significantly (from 5.5mv to 0.16mv). |
