TL;DR: In this article, the reliability performance of 1-µm Pt-sunken gate InP HEMT MMICs on 4-inch InP substrates was evaluated under elevated temperature lifetesting.

Abstract: This paper describes the design and development of a state-of-the-art dual-channel 183 GHz InP based Monolithic Microwave Integrated Circuit (MMIC) radiometer. This is the world's first reported monolithic radiometer that operates at 183 GHz enabling high precision micro-miniature sensing of atmospheric chemistry components in this band. The radiometer features the following key components: a plug-in front end low noise amplifier module utilizing a broadband InP MMIC that sets the system noise figure, a low loss waveguide diplexer module, waveguide-to-microstrip transitions fabricated on Z-cut quartz, a mechanical design that can be easily modified to be hermetic, dual-channel output allowing double sideband detection, and a combination of HEMT and HBT InP and GaAs MMIC active components.

TL;DR: In this article, a 0.5-100 GHz suspended stripline filter and low-loss passives based on MMIC wafer fabrication techniques and heterogeneous integration through gold-gold compression bonds were developed.

TL;DR: In this paper , the potential of cell-based delivery of oligonucleotides to cancer cells via two naturally occurring intercellular pathways: gap junctions and vesicular/exosomal traffic was examined.

TL;DR: In this paper, a method for forming a semiconductor device for sub-millimeter wave operation was proposed, which allows the production of the semiconductor devices to be suitable for a submillimeter-wave operation, where the conformal layer is selectively removed from the photoresist layer and a bottom portion of the window to form dielectric sidewalls.
