摘要

本文介绍了一种用于下一代无线应用的250纳米InP HBT技术的D波段低噪声放大器(LNA)。LNA的实测峰值增益为13db, 3db带宽大于20ghz (120 ~ 140ghz)，该频段的实测噪声系数小于6db。在使用全芯片电磁(EM)模拟的测量过程中，观察到模拟中3db带宽的减少，这归因于衬底波。EM模拟表明，部分或完全去除InP衬底的背面金属化，金属-1接平面上的孔，或策略性地放置穿过衬底的通孔，都可以抑制这些衬底波。据作者所知，这是InP 250nm HBT技术中的第一个120 - 140 ghz LNA。

A 120–140-GHz LNA in 250-nm InP HBT

This letter presents a $D$ -band low-noise amplifier (LNA) in 250-nm InP HBT technology for the next-generation wireless applications. The LNA has a measured peak gain of 13 dB, a 3-dB bandwidth greater than 20 GHz (120–140 GHz), and a measured noise figure (NF) of less than 6 dB in the band. A reduction in the 3-dB bandwidth from simulation was observed during the measurements which was attributed to the substrate waves using full chip electromagnetic (EM) simulation. EM simulations show that a partial or complete removal of the back side metallization of the InP substrate, holes in metal-1 ground plane, or a strategic placement of through-substrate vias suppress these substrate waves. To the authors’ knowledge, this is the first 120–140-GHz LNA in the InP 250-nm HBT technology.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
