| 摘 要： | 研究了一种基于石英基片的0.1 THz频段的鳍线单平衡混频电路，混频电路的射频和本振信号分别从WR10标准波导端口通过波导单面鳍线微带过渡和波导微带探针过渡输入，中频信号通过本振中频双工器输出。这是一种新型的混频电路形式，与传统的W波段混频器相比，混频电路可以省略一个复杂的W波段滤波器，具有电路设计简单、安装方便的特点。该电路使用两只肖特基二极管通过倒装焊工艺粘结在厚度为75 m的石英基片上，石英基片相对传统基板，可以极大提高电路加工精度。在固定50 MHz中频信号时，射频90~110 GHz范围内，0.1 THz混频器单边带变频损耗小于9 dB。

| Abstract: | This design, fabrication and test of a 0.1 THz fundamental finline single-balanced mixer circuit on a single quartz substrate was presented. The local oscillator(LO) input signal was feeded from WR10 waveguide to a suspended microstrip line, the radio frequency(RF) input signal was also feeded from WR10 waveguide to a finline, and the intermediate frequency(IF) signal was taken to the output port through a LO-IF duplexer. This novel mixer circuit can omit a complex W-band filter compared to traditional mode. The circuit features simple design and easy assemblage. A pair of flip-chipped diodes rested on the 75 m thick quartz substrate, which could improve the size precision of circuit, constitute the basic balanced mixing circuit. After the mixer circuit is fabricated, it owns a 90-110 GHz operating frequency, and its single side band conversion loss is better than 9 dB when the IF is fixed at 50 MHz. |
