This paper presents the design and analysis of Ultra Wideband (UWB) mixer in 65nm CMOS technology. To achieve the optimized performance, a new mixer topology is suggested. The performance parameters of the mixer viz.: conversion gain, Noise Figure, linearity and power consumption are addressed in this paper. The simulation results of the new mixer topology suggested in this paper achieves the r...

Composite material based on Fe3Si micro-particles and Mn-Zn nano-ferrite was prepared using powder metallurgy technology. The sol-gel followed by autocombustion process was used for synthesis of Mn0.8Zn0.2Fe2O4 ferrite. 3 wt.% of mechanically milled ferrite was mixed with Fe3Si powder alloy. Mixed micro-nano powder system was homogenized by the Resonant Acoustic Mixing using ResodynLabRAM Mixer...

In this paper, we present results on the noise performance of the waveguide Niobium Titanium Nitride (NbTiN) superconducting hot electron bolometer (HEB) mixers, cryogenically cooled by a 4-K close-cycled refrigerator. The NbTiN superconducting HEB mixer is fabricated on a crystalline quartz substrate, and is mounted in a waveguide mixer block for RF and LO coupling. At 0.81 THz, the uncorrecte...

A highly linear down conversion mixer with moderate gain used for 2.4GHz RF applications is presented in this paper using 0.18μm CMOS technology. The proposed mixer incorporates current bleeding technique & degenerative resistors to improve linearity and conversion gain. Also the negative feedback configuration of the circuit gives flat conversion gain increasing the overall bandwidth. The simu...

In this paper, a 2.4GHz low power downconversion mixer with high linearity for direct-conversion receivers based on a standard 0.18um CMOS technology is proposed. In the circuit design, Gilbert cell architecture and Common-Gate configuration are used. A simple buffer is applied in the IF output. Simulation results show that the mixer can operate at 2.4GHz and obtain the conversion gain of 11.08...

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.

The NRAO CDL is preparing to construct test receivers for use in production of the Band-6 mixer-preamps for ALMA. The discussion below applies primarily to the mixer-preamp to test receiver interface, but should also be useful as a guide to the mixer-preamp interface with the cartridges — all the listed connections will be available on the mixer-preamp and can be used as desired by the cartridg...

This paper is a design and implementation of a monitoring and control system for industrial mixer using PLC .This mixer used for an effective, reliable and highly flexible method for the control of processes within an Industrial environment. The objective of this study is to simulate the control an industrial mixer and by doing this we can develop a program that can be used for the actual imple...

In spectral line measurements, wanted (image) sideband can be eliminated by using an o reduce local oscillator noise, balanced mixers can ealize image separating and balanced mixers using RF circuits, but they are difficult to fab...

High resolution frequency study and phase-locking have been performed on a terahertz quantum-cascade vertical-external-cavity surface-emitting-laser operating around 2.5 THz. A subharmonic diode mixer is used to down convert the THz signal 100 MHz intermediate that phase locked stable microwave reference. Between 90-95% of QC-VECSEL within 2 Hz multiplied RF reference, amplitude fluctuations or...
