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...

This paper presents a 20–32-GHz wideband BiCMOS mixer with an IF bandwidth of 12 GHz. The mixer utilizes an inductive peaking technique to extend the bandwidth of the downconverted IF signal. To our knowledge, the proposed mixer achieves the widest IF bandwidth using silicon-based technologies in -band. Analytical expressions for the conversion gain and output noise of the proposed mixer are pr...

A room-temperature Schottky diode-based WM-86 (WR-0.34) harmonic mixer was developed to build high-resolution spectrometers, and multipixel receivers in the terahertz (THz) region for applications such as radio astronomy, plasma diagnostics, and remote sensing. The mixer consists of a quartz-based local oscillator (LO), intermediate-frequency (IF) circuits, and a GaAs-based beam-lead THz circui...

The passage of light or of electrons through a disordered medium is modified in the presence of resonances. We describe a simple model for this problem, and present first results.

This work presents the design of a low power upconversion mixer adapted in medical remote sensing such as wireless endoscopy application. The proposed upconversion mixer operates in ISM band of 433 MHz. With the carrier power of -5 dBm, the proposed mixer has an output inferred 1 dB compression point of -0.5 dBm with a corresponding output third-order intercept point (OIP3) of 7.1 dBm. The desi...

A CMOS low-noise amplifier (LNA) and mixer for a GPS front end is described. At 1.586Ghz the LNA minimum noise figure (NF) is 2.8dB, input third order intercept point (IIP3) is 2.45dB and forward gain is 30dB. With a 1.573Ghz local oscillator (LO) and a 1.586Ghz RF input the mixer minimum NF is 6.1dB, IIP3 is 12dB and a conversion gain of -3dB. The LNA and mixer consume 58mW of power from a 1.8...

A 2.4 GHz CMOS up-conversion mixer using novel current mirrors based on chartered 0.18 μm RF CMOS technology for 2.4 GHz wireless sensor network (WSN) application is presented in this paper. The current-reuse current-mirror and current-bleeding technique are used in the driver and switching stages of the mixer, respectively. The post-layout simulation results demonstrate that the novel up-conve...

A double balanced Gilbert-cell class-A amplifier bleeding mixer (DBGC CAAB mixer) is proposed and implemented. The injection current is utilized to amplify the local oscillator (LO) signal to improve the performance of the transconductor stage. The DBGC CAAB mixer achieves a conversion gain of 17.5 dB at −14 dBm LO power, and the noise figure is suppressed from 45 dB to 10.7 dB. It is important...

In this paper a low power CMOS sub-harmonic mixer based on the Gilbert cell for 2.4 GHz ISM band application is presented, in which the position of the switching and transconductance stages of mixer has been exchanged. A tuning out inductor has been used between the RF and LO switching stages to improve the linearity and noise figure, and also to enhance the conversion gain of the Mixer. The ut...
