Abstract为了在亚毫米波波段进行遥感探测,研制了450 GHz的二次谐波混频器,混频器的核心部件是一对反向并联的肖特基二极管,长度为74 mum,截止频率高达8 THz.在石英基片上搭建悬重微带的匹配电路,并采用一分为二的金属腔体.在二极管的仿真中获得二极管管芯的输入阻抗,然后考虑二极管的封装、匹配电路,仿真得到混频器的单边带变频损耗为8.0dB,所需本振功率为4 mW.测试表明,本混频器的单边带变频损耗的最佳值为14.0 dB,433 ~451 GHz之间的损耗小于17.0 dB,3 dB带宽为18 GHz,所需的本振功率为5 mW.
Other AbstractTo realize remote sensing at sub-millimeter wavelengths,a 450 GHz sub-harmonic mixer was studied. An anti-parallel pair of Schottky diodes is the key component in the mixer. The length of the diodes is 74 mum,and the cutoff frequency of diodes is up to 8 THz. The suspended microstrip matching circuit was built on quartz,and the metal block was cut into two halves. The diode embedding impedance was calculated. The diode package and the matching circuit were integrated in the mixer model. The predicted single side band (SSB) conversion loss is 8. 0 dB,with 4 mW of local oscillator power. Measured results indicate that the lowest measured SSB conversion loss is 14. 0 dB, with 5 mW of local oscillator power. The loss is below 17. 0 dB in the band from 433 ~ 451 GHz,with a 3 dB bandwidth of 18 GHz.
