研究了一种基于石英基片的0.1THz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75μm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50MHz中频信号时,射频90~110GHz范围内,0.1THz混频器单边带变频损耗小于9dB。
A 0.1 MHz FSB single-balanced mixer circuit based on a quartz substrate was studied. The RF and local oscillator signals of the mixer circuit were respectively transmitted from the WR10 standard waveguide port through the waveguide single-sided finned microstrip transition and the waveguide microstrip Pin transition input, IF signal output by the intermediate frequency diplexer. This is a new type of mixing circuit. Compared with the traditional W band mixer, the mixing circuit can omit a complicated W-band filter and has the advantages of simple circuit design and convenient installation. The circuit uses two Schottky diodes bonded by flip-chip bonding process on a quartz substrate 75μm thick, the quartz substrate relative to the traditional substrate, can greatly improve the circuit processing accuracy. In the fixed 50MHz IF signal, the RF 90 ~ 110GHz range, 0.1THz mixer single sideband frequency conversion loss is less than 9dB.
