PY - 2011 DA - 2011// TI - The stability of a terahertz receiver based on a superconducting integrated receiver T2 - Supercond. Sci. Technol. JO - Supercond. Sci. Technol. SP - 035003 VL - 24 IS - 3 KW - SIS mixer KW - SIR KW - stability AB - We present the results of stability testing of a terahertz radiometer based on a superconducting receiver with a SIS tunnel junction as the mixer and a flux-flow oscillator as the local oscillator. In the continuum mode, the receiver with a noise temperature of 95 K at 510 GHz measured over the intermediate frequency (IF) passband of 4-8 GHz offered a noise equivalent temperature difference of 10 ± 1 mK at an integration time of 1 s. We offer a method to significantly increase the integration time without the use of complex measurement equipment. The receiver observed a strong signal over a final detection bandwidth of 4 GHz and offered an Allan time of 5 s.
