This paper describes an 84-116 GHz Nb/Al-oxide/Nb SIS mixer with multi-octave IF bandwidth and quantum-limited sensitivity. The mixer can be integrated with a three-stage 4-12 GHz HFET preamplifier or fitted with a coaxial connector for operation with an external isolator and IF amplifier. An 84-116 GHz receiver using the mixer with an integrated 4-12 GHz HFET preamplifier has a double sideband...

We developed a confocal microscopic method for a quantitative evaluation of the mixing performance of a three-dimensional microfluidic mixer. We fabricated a microfluidic baker's transformation (MBT) mixer as a three-dimensional passive-type mixer for the efficient mixing of solutions. Although the MBT mixer is one type of ideal mixers, it is hard to evaluate its mixing performance, since the...

Computational fluid dynamic (CFD) simulation is an effective research approach for understanding velocity fields used in process and equipment intensification. It was found that mixer-settler used in rare earth metal extraction process was unsatisfying in large amount of liquid backlogged, high energy consumption and longtime settling process. In this paper, CFD simulations and experiment valid...

material balance around process has been conducted by using mixer output equations. a method based on mason's theory has been proposed to develop mixer output equations.

I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to...

Identity Mixer is an anonymous credential system developed at IBM that allows users for instance to prove that they are over 18 years old without revealing their name or birthdate. This privacy-friendly technology is realized using zero-knowledge proofs. We describe a formal model of Identity Mixer that is well-suited for automated protocol verification tools in the spirit of black-box cryptogr...

This paper describes how to response of oscilloscopes, especially at low fre MHz to 1 GHz. The method uses the phas standard mixer calibrated by three-mixer reference phase. We describe basic principles obtained using a balanced mixer and a real-tim GHz BW).

A low-voltage and low-power RF mixer for WCDMA applications is presented. The paper presents a novel topology mixer that leads to a better performance in terms of isolation and power consumption for low supply voltage. The measuring results of the proposed mixer achieve: 7dB power conversion gain, 10.4dB double side band (DSB) noise figure, -2dBm input third-order intercept point (IIP3), and th...

A 3–8 GHz broadband mixer is presented in this paper. This broadband mixer is low power and high conversion gain. It provides current reuse and ac-coupled folded switching. This mixer is designed in TSMC 0.18-μm CMOS technology. This broadband mixer achieves simulated conversion gain of 9 ± 1.5 dB, a single sideband noise figure lower than 15.2 dB and IIP3 batter than −7 dBm. From 3–8GHz, at su...

Recently, a next-generation heterodyne mixer detector— a hot electron bolometer (HEB) mixer employing a superconducting microbridge—has gradually opened up terahertz-band astronomy. The surrounding state-of-the-art technologies including fabrication processes, 4 K cryostats, cryogenic low-noise amplifiers, local oscillator sources, micromachining techniques, and spectrometers, as well as the HE...
