RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

See-Through Semiconductors

If you think you've had trouble in the past trying to find small components that you drop in the lab, you haven't seen anything yet - literally. The new Gallium Nitride (GaN) ICs that feature both high frequency and high power density are as clear as glass. Their high energy band gaps allow visible light photons to pass right through without absorption, which we perceive as color. The only visible feature on the chips will be the metallized bonding pads. It will be interesting to "see" what kind of chip graffiti shows up on these devices!
