Watkins Johnson Tech-Notes Archive

Believe it or not, there was a time when the Internet did not exist, and getting quality information (or perhaps more notably, bad information) was not so easy. Waaaaayyyyyy back in the 1970s and 1980s when I was new to the electronics design world, offices, cubicles, laboratories, company technical libraries, even hallways, were piled high with reference books, magazines, component books, applications notes, datasheets, white papers, and every other form of information that might be useful or someone probably found useful at some time in the past.

Now, of course, the preferred source for information is the Internet, particularly from trusted sources like universities, book publishers, RF Cafe, etc. The problem is that a lot of the old data that was uniquely useful, has not been archived on the Web.

Such is the case with an exceptionally useful set of Tech-Notes that appeared in the Watkins Johnson parts catalogs of yore (circa 1980). It is quite difficult to locate those notes, especially since websites keep moving the files around, breaking links. So, as a matter of public service, I am making them available here.
