We'll discuss shredded metal, smoldering circuits and whatever else seems interesting. My target audience is . . . me! If you're not me and you're here anyway, I hope you enjoy the site. Feel free to leave me feedback.
This site is in the process of being redesigned. Thanks for your patience!
This site is the collective ramblings of a person with many varied interests. It's specifically not about work-related stuff because there are better venues for that. The things I do for a living are my main passion, but thankfully life gives us many more avenues for advancement and learning.
In this project, we open up a cavity duplexer from a Sprint / Nextel iDEN cellular repeater. We see the interior where all the black magic happens, attempt a repair and reassemble it against all odds of success.
One of the important components of my GPS-disciplined oscillator project is the signal distribution board. The oscillator sends its pure signal through an isolation / buffer amplifier, then through an RF splitter. The splitter sends one copy of the signal to the digital control circuits and another copy to the distribution board.
