摘要

本研究提出了两种实用的塑料封装，用于实际的太赫兹应用，分别使用塑料引线芯片载波(PLCC)和嵌入抛物线天线。在封装的上表面安装一个谐振隧道二极管(RTD)振荡器，其上集成了偶极子天线，用于测量辐射特性。与RTD裸芯片相比，PLCC的天线增益提高了5 dB，而抛物线天线类型的天线增益提高了17 dB。该团队还利用plc封装的RTD作为振荡器和检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说明了该封装的有用性。

Development of Practical Terahertz Packages for Resonant Tunneling Diode Oscillators and Detectors

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.
