We discuss performance of submicron size hotelectron bolometer (HEB) mixers made from thin MgB2 superconducting films. With a superconducting transition temperature of 30K, such THz mixers can operate with high sensitivity at temperatures up to 20K. Due to very small dimensions local oscillator (LO) power requirements are rather low. In the intermediate frequency (IF) band of 1-3GHz the double...

Domestic Hot Water (DHW) production constitutes a significant proportion of the energy demand modern buildings, and as building envelope is improved share increases. This article shows results from measurement campaign on two equal hotel blocks, in same hotel. There are different basin shower mixing taps installed one with original mixers (13–14 l/min) touch-free operated water saving (5–6 l/mi...

In this paper, the research advances in SIW-like (Substrate Integrated Waveguide-like) guided wave structures and their applications in the State Key Laboratory of Millimeter Waves of China is reviewed. Our work is concerned with the investigations on the propagation characteristics of SIW, half-mode SIW (HMSIW) and the folded HMSIW (FHMSIW) as well as their applications in microwave and millim...

Image-reject mixers (IRMs) and single-sideband mixers (SSMs) play a key role in many of today’s microwave and rf systems [1, 2, 3]. IRMs and SSMs reduce system cost and complexity by removing the need for expensive preselection, and one or more stages of upor downconversion. IRMs simplify downconversion by employing phase-cancellation techniques to separate the downconverted products resulting ...

The powder-blasting method is used to fabricate structures with a three-dimensional topography in glass using elastomeric masks. The relation between the mask opening width and the erosion depth is exploited to fabricate microstructures with varying depth in a single micropatterning step. As an application, planar three-dimensional micro-mixers were fabricated, which consist of a repeating conv...

In this paper, the research advances in silicon based millimeter wave and THz ICs in the State Key Laboratory of Millimeter Waves is reviewed, which consists of millimeter wave amplifiers, mixers, oscillators at Q, V and W and D band based on CMOS technology, and several research approaches of THz passive ICs including cavity and filter structures using SIW-like (Substrate Integrated Waveguide-...
