摘要

这封信介绍了WR-3.4波导和3毫米直径的硅透镜模块，其中包含h波段InP检测器集成电路（ic）。所有的探测器，包括集成电路和模块，都表现出优异的性能。该IC在270 GHz时的响应度为960 kV/W，噪声等效功率（NEP）为25 fW/Hz0.5，并有一个覆盖整个H波段的有源前置放大器，增益超过20 dB。一种自由空间测量方法可以准确地评估透镜模块的辐射指向性。尽管馈源天线失配会造成损耗，导致封装效率相对较低，仅为6.4%，但该透镜模块的性能仍然令人印象深刻，在270 GHz时的响应率为61 kV/W， NEP为394 fW/Hz0.5。

270 GHz InP HBT Detector Modules Utilizing WR-3.4 Waveguide and Silicon Lens

This letter introduces WR-3.4 waveguide and 3-mm diameter silicon lens modules, which house H-band InP detector integrated circuits (ICs). All detectors, including IC and modules, demonstrate excellent performance. The IC achieves a responsivity of 960 kV/W and a noise equivalent power (NEP) of 25 fW/Hz^0.5 at 270 GHz, aided by an active preamplifier that covers the entire H band with over 20 dB gain. A free-space measurement method accurately assesses the lens module's radiation directivity. Despite losses arising from the feed antenna mismatch, leading to a relatively low packaging efficiency of 6.4%, the lens module still performs impressively, delivering a responsivity of 61 kV/W and an NEP of 394 fW/Hz^0.5 at 270 GHz.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
