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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

Hi Everyone,

Does anyone know where can I find an RF/Microwave Power Amplifier in the range of 1-2.5 GHz up to 500 Watts. I found major manufacturers that they sell them but nobody even has it for sell either. Nothing readily availbale. My Frequency of interest is at 1.5 GHz and 2 GHz. Any help would be appreciated.

Thanks,

Hi,

That's a good question. I am trying to qualify one of our parts that is able to carry such high power at that frequency. I can not say where would it be used but it is for space, millitary application.

Well that answers the "what on earth...." part of my questions. Thanks.

If all you want to test is power handling then the 2500 MHz part of your quest is easy... get a $30 microwave oven from walmart. They are 600 W or so.

As for your whole frequency range, your question is way out of my areas of knowledge. I expect someone here will answer your question soon. Good luck.
