MM wave p-i-n diode development

Teratech Components Ltd(Teratech)正在请求支持，以开发一种新型产品：空气桥p-i-n二极管，以补充Teratech的各种空气桥肖特基二极管。电磁频谱的大部分已经被很好地理解和利用，但微波和红外之间的太赫兹(THz)区域仍然很大程度上仍未被探索。能够以比微波更高的空间分辨率看清遮蔽介质材料的能力，以及高速数据传输的潜力，使得太赫兹光谱特别令人感兴趣。使用与当前肖特基产品中使用的类似的气桥接触结构，p-i-n二极管将被设计为工作在至少是目前可用的商业设备的两倍的更高频率。这些设备的主要用途是开关和衰减电路；这些电路在热成像(用于安全和医疗目的)、毫米波雷达、亚毫米光谱分析、处理技术、亚波长分辨率的近场成像和高带宽数据传输等各种应用中都是非常重要的。这些应用和其他应用都得到了新兴的国际毫米和亚毫米测试仪器市场的支持。

Teratech Components Ltd (Teratech) is requesting support to develop a new type of product: the airbridged p-i-n diode to complement teratech's wide range of airbridged schottky diodes. Most parts of the electromagnetic spectrum are well understood and exploited, but the terahertz (THz) region between microwaves and infrared is still largely unexplored. The ability to see through obscuring dielectric materials with higher spatial resolution than with microwaves, and the potential for high speed data transfer, makes the THz spectrum of particular interest. Using airbridged contact structures, similar to those employed in current schottky products, p-i-n diodes will be designed to operate to upper frequencies at least twice that of currently available commercial devices. Primary uses for these devices are within switching and attenuation circuits; which are usd in applications as diverse as thermal imaging (for security and medical purposes), millimetric radar, sub-millimetre spectroscopy, process technology, near field imaging at sub-wavelength resolution and high bandwidth data transfer. These, and other applications, are backed by an emerging international market in millimetre and sub-millimetre test instrumentation.
