| 英文摘要 | We present design and evaluations of a submillimeter double-ridged waveguide ortho-mode transducer (OMT) for ALMA Band 8 (385-500 GHz) cartridge receiver. The measured transmission loss of the OMT at 4 K was 0.4-0.5 dB according to noise measurements with an SIS mixer. The polarization isolation was measured to be larger than 29 dB from quasioptical measurements. The OMT consists of a BI center dot ifot junction and a double-ridged guide. A robust design with allowable mechanical errors of 20 mu m has been demonstrated. |
