在这项研究中，提出了两种类型的实际塑料封装的实际太赫兹应用，通过使用塑料引线芯片载体（PLCC），也通过嵌入抛物面天线。一个共振隧穿二极管（RTD）振荡器的顶面上的偶极天线集成安装在封装测量的辐射特性。与RTD裸芯片相比，PLCC的天线增益提高了5 dB，而抛物面天线类型的天线增益提高了17 dB。该团队还利用PLCC封装的RTD作为振荡器和探测器来制造太赫兹成像模块。通过1.25 mm像素间距的线扫描获得的透视图像阐明了该封装的有用性。
The two types of practical plastic packages are proposed in this study for practical terahertz applications by using a plastic leaded chip carrier (PLCC), and also by embedding a parabolic antenna. A resonant tunneling diode (RTD) oscillator onto the top surface of which a dipole antenna is integrated is mounted in the packages to measure the radiation characteristics. The antenna gain is improved by 5 dB for the PLCC, while 17 dB for the parabolic-antenna type, compared to that of the RTD bare chip. The team also fabricates terahertz-imaging modules by utilizing PLCC-packaged RTD's as an oscillator and a detector. A perspective image obtained by line-scan with 1.25-mm pixel pitch elucidates the usefulness of the package.
