It has been my belief† for a long time that the vast majority of print magazine advertisements are never seen by potential customers because very few of those potential customers ever bother to pick up a print magazine. More than a decade ago (around 2007) when I was spending my last days working in a corporate environment, I do not ever recall seeing anyone reading a trade magazine, be it Microwave Journal, Microwaves & RF, Electronic Design, EE|Times, or any of the others. In fact, most of the magazines I saw were deposited in the mail room recycle or trash bin before they ever made it to an engineer's, technician's, or manager's desk. That is not to say or imply the magazines are not excellent - they are, indeed - but even back then most people were getting their needed information online. Being able to show a print version circulation number to advertisers does not in any way correlate directly to the number of potential customers who will ever see their advertisements.

I still like to read through the print versions of magazines to look for useful fodder for posting here on RF Cafe (I do the same thing for my hobby website, AirplanesAndRockets.com). The quality of the advertisements is outstanding; artists and layout folks at the companies do amazing work. It's a shame almost nobody will ever see and appreciate it. I see it, and I appreciate it.

Oddly enough, almost none of these ads (usually full-page or even 2 page) are made available on the companies' websites. I don't know why ... they should be. Online versions of the magazines usually include advertisement placements like in the print versions.

In an effort to make what I consider to be very well done and useful information available to engineers, technicians, managers, students, and hobbyists (who often are a combination of two or more of the aforementioned), I am going to scan and post a sampling of the advertisements here on RF Cafe. With RF Cafe prominence in Internet searches using major search engines, there is a good likelihood that one of the company advertisements will appear - especially in an image search. Images are unaltered from the original scan other than for contrast and lightness in order to minimize noise.

If any company is opposed to having its advertisement displayed here, please send me an e-mail and I will remove it immediately. There is no charge or expectation of an in-kind promotion, favor, or payment of any form. This is a service to RF Cafe visitors and to the companies who keep them employed and supplied with needed products and services. In fact, that is what RF Cafe has always been about since its inception in July of 1999!

† This is my opinion based on personal observation. The situation might change over time without my noticing it.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

1996 - 2024


Kirt Blattenberger,


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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
