Maxim Integrated Product’s new MAX2042 upconverting and downconverting, double-balanced passive mixer operates at 2 to 3 GHz. The SiGe (silicon-germanium) chip includes an internal local-oscillator buffer and two baluns.An old material for batteries turns out to have another nature 12/3/2009
A team from Johns Hopkins University recently found that a nonsemiconductor that has long found use as a conductor turns out also to be, in a different orientation, an insulator, with properties useful in constructing MOSFETs. The material, solution-deposited beta alumina, forms when aluminum oxide from solution forms solid layers of crystals.In-Depth
