mixer-ic-component


The basic configuration of a single mixer is that it has two inputs and one output. It multiplies or mixes the carrier signal, either RF or intermediate frequency (IF) depending on an up conversion or down conversion mixer, with another input from the local oscillator (LO). The LO signal input terminal is used to assist in the heterodyning process, produces the difference and sum frequencies of the two input terminals of interest.

Planar laminar mixer
free download

ABSTRACT Standard approaches to fluid mixing typically rely on turbulence, three- dimensional flows, or mechanical actuators, none of which can be easily implemented in the planar lithographic MEMS design environment. The authors present an approach to mixing In polymer-based nanocomposites, because of the large fraction of the nanoparticle atoms that reside at the interface, there would be a strong interface interaction between filler and polymer. The mechanical properties of nanocomposites would improve significantly at a low
