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 ...

Important: RF Stencils for Visio v2 will not work with Visio 5 or earlier versions. It has been verified to work in Visio 2000 through 2010. See the known issues info a the bottom of this page.
Of course if you have the non-colored version, you can always just add your own color. However, some of the newer symbols have been changed a bit, and entirely new symbols have been added. Most of the stencils are for RF, microwave, and wireless drawings, but a few are included for standard electronic schematics since often the two types are combined. Visio has a lot of built-in symbols for electronics.
The block diagram at the right is an example of what can be done with the new symbols. Connection points are provided on everything for exploiting Visio's built-in Connector lines that automatically follow a symbol if it is moved on the page (it's easy enough to add them yourself to the v1 version). Combined with the selection of objects supplied with the Visio software, everything you need to create presentation quality drawings is available.
The EIA standard equipment rack and test equipment stencils now have text that scales with the stencil as it is varied. Doing so required modifying the ShapeSheets with an equation in the text size field. It was a lot of work, but definitely worth the effort. The v1 stencils required you to manually re-size the text if you resized the racks or TE. As with the other v2 components, color has been added to everything.
As with the v1 rack & TE stencils, they are built full-size at a 1:1 scale, so everything is directly measurable without scaling. Your page size is set to the real-life size and everything will fit exactly as it would if you printed it out full-size. Of course, you can tell Visio to print it to fit on a standard size piece of paper.
To right and left are screen captures of the actual Stencil windows that show all the available components. RF Stencils for Visio v1 had two versions of most components - both horizontally and vertically oriented - in order to accommodate the grouped text fields for parameter specification.
Rather than clutter the stencil selection with essentially redundant components, a single version is provided, and the specification text, where applicable, is provided as a separate component. You can of course add your own text objects to the drawing, just as you can add any other type of Visio built-in objects.
Says Bob: "I needed a Handheld DMM stencil, so I created one loosely modeled on a Fluke 289. Attached is a *.vsd file containing two versions -- the "Original" is grouped, but editable; the Metafile version is scalable (created by copying the original and doing a "Paste Special" in metafile format). "
How to open these stencils in Visio 2010?
** Make certain that the Color Themes are set to "None" **
In Visio 2013, you will probably need to change the File Block Settings that have been added in 2013 for security purposes. Please see the Microsoft support page for detailed instructions on File Block Settings (it's easy to do).
