Cool Pic

RF Cafe Cool Pic - Official temperature monitoring station - one of many similar situations worldwideImagine if the standard physical meter bar in France was stored in a room where a coffee machine was set next to it after 100 years of being alone. Suddenly, metrologists began to notice that the meter was seemingly getting longer. Alarmists began screaming that the Earth was getting smaller, portending certain doom as it would surely fracture and crumble. Former high-ranking politicians and preferred group leaders became multi-millionaires by exploiting the lack of applied rigor in the scientific method. Entire economies were upset because anyone questioning the veracity of measurements of exalted scientists was impugned as a "hater of science." Nah, it could never happen.
Smorgasbord

A Backwards Extension
of Moore's Law

source: (Intel)
RF Cafe Smorgasbord - Computing power vs. electrical power following Moore's Law pathAssuming the data used is accurate, this chart indicates that Moore's Law describing (not governing) IC evolution, when applied to computing efficiency, reaches back to the first digital computer - ENIAC. A study titled, "Assessing Trends in the Electrical Efficiency of Computation Over Time" found that when computing power as a function of electrical power usage is plotted, it doubles approximately every 18 months. Engineers expect the trend to continue. If the chart had resembled a hockey stick, I would have dismissed it as junk science.

Videos for Engineers

RF Cafe Videos for Engineers - MIT OpenCourseware MOSFET AmplifiersA few years back, MIT began a program of publishing videos of many full courses, including the electrical engineering curriculum. This particular video from course number 6.002 covers MOSFET amplifiers. On-screen captioning follows the popular Professor Anant Agarwal's performance as he speed-writes/draws on the multi-layered electric chalkboard. A full transcript is provided for each lecture. It is a great way to brush up for an impending interview.

AWR just announced it is giving away full copies of its MWO and VSS software to qualified BS, MS, and PhD engineering grads. This is a gift worth thousands of dollars! Pass this news along.
Cool Product

RF Cafe Cool Product - ISEE has developed a compact, low-cost, robust 24 GHz radar sensor (ISM Band included) for automotive, industrial or home applications. Consisting of a planar antenna, a 24 GHz front-end and an OMAP3530 processor unit for signal processing, it measures distances (25 m ±20 mm typical), velocity or properties of objects with RF Cafe Cool Product - ISEE 24 GHz Radar Antenna Radiation Patternhigh accuracy. The system uses a linear FM CW signal. Lunar Lander X-Prize contestants were all begging for something like this a couple years ago (I know because I received many e-mails looking for such a product). Price is only 145€ ($200).
