An experimental study of a balanced mixer based on 2A116A-1 diodes was carried out.Conversion losses were measured in the input frequency range 2450 ± 45 MHz during downconversion to an intermediate 2125 MHz. Conversion loss does not exceed 20 dB anarrow band 2440±10 The amplitude characteristic taken, from which itcan be seen that it is linear for signals up 0 dBm (1 mW). dependence conversion...

Abstract Static mixers (SMs) are widely used in applications that involve chemical reactions, heat transfer, blending of fluids, or some combination these. Accurately evaluating the performance SMs is critical for appropriate selection these devices. Traditional approaches parameters separately evaluate mixing level and energy spent (i.e., pressure drop) but do not account both simultaneously. ...

In this paper, a 1.2-V RF front-end realized for the personal communications services (PCS) direct conversion receiver is presented. The RF front-end comprises a low-noise amplifier (LNA), quadrature mixers, and active RC low-pass filters with gain control. Quadrature local oscillator (LO) signals are generated on chip by a double-frequency voltage-controlled oscillator (VCO) and frequency divi...

This paper describes a 2 GHz CMOS active balanced downconversion I/Q mixer in a TSMC0.18m process for a WCDMA receiver. The mixer achieves a conversion gain of 16 dB and a double side band (DSB) NF of 13.8 dB. The mixer's IIP3 is 12.12 dBm. It consumes approximately 5 mA of current from a 1.8-V power supply. The 12.12 dBm IIP3 fulfils the UMTS requirements for a mixer design.

This paper describes a 1.5-V 5 GHz I/Q down conversion mixer in a 0.18-μm CMOS process. The mixer achieves a conversion gain of 12.7 dB within 1-dB compression point (iCP1dB) of -15.83 dBm. It also achieves a double side band (DSB) NF of 13.5 dB. The mixer's IIP3 is -5.94 dBm. The mixer consumes only 5.72 mA of current from a 1.5-V power supply.

A detection scheme based on the artificial immune system (AIS) paradigm was developed for specific classes of aircraft jet engine failures including throttle, burner fuel flow valve, variable nozzle area actuator, variable mixer area actuator, low-pressure spool speed sensor, low-pressure turbine exit static pressure sensor, and mixer pressure ratio sensor. The Modular Aero-Propulsion System Si...

Elastic instabilities are identified as flow occurring in the presence of low inertial effects, induced by combination strong elastic forces with nonlinearities flow. In continuous laminar mixing applications, onset these is likely to occur window applied rates; therefore, it important understand effects their on process efficiency. this work, we investigated experimentally two tubular static m...
