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has not been archived on the Web.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. All copyrights are hereby acknowledged.
