[Editorial]
Handling Power Requires Imagination

Jack Browne  |  ED Online ID #22230 |  December 10, 2009

High-power microwave signals can wreak havoc in the wrong hands. While many microwave applications operate at relatively low power levels, often in the milliwatt range, some systems, such as radar and communications transmitters, must channel robust amounts of high-frequency energy. And knowing how to design components to handle hundreds or even thousands of watts of RF/microwave power requires skill and imagination above and beyond the models in a computer-aided-engineering (CAE) simulator.

During a recent visit to Micronetics, a company with no small knowledge of building components and assemblies that can channel high-power signals, Mechanical Designer Mike Hebert was good enough to share a look at a high-power test rig, complete with heavily amplified test source. The foresight needed to operate with high-power levels, to understand potential hotspots, and even to anticipate the limitations of coaxial connectors and waveguide flanges, was obvious in his setup and test planning. The high-power arena is not for everyone, but it is an intriguing part of RF/microwave design that will receive more attention within the pages of Microwaves & RF (as well as in three supplements dedicated to military electronics technology) in the coming year.

This is ridiculous. Where's the article? This was two small paragraphs of introduction and no real information.

I think he's really referring to medium power (under 1 MW).

I work in the "High Power" arena....you could probably do a complete edition on the cooling systems needed to support...why not consider a Military High Power feature at some point? I'm not going to go heavy on the global criticism, but this grabbed my attention and went nowhere.

Not worth the electrons it took to open the "article". Something with a bit more substance next time please.

We do power at ~100 MHz, kW level. This wasn't worth much as an article, and could have been written in 2-3 sentences. What little info is here is valid. In high power stuff, the packaging makes a huge difference and so do the RF transmission lines.

Just two paragraphs. Not a glimmer of imagination anywhere.

Given that this "article" was the lead item of the email newletter, and was featured in that newsletter's headline, I had expected an ARTICLE, not a 10-line "teaser". Like maybe, a picture of the test fixture that you found so interesting, some examples of the kind of damage to hequipment of person that can result from not handling the stuff properly, ... and maybe some real numbers to let us know how much power this guy thinks is a lot.

Was this an editorial, or a marketing plug?

Was that really worth writing? It certainly didn't seem to be worth reading. Please either put a little more into your "articles" or don't write them at all.

Ooooh, more high-power coverage within the pages of Microwaves & RF Magazine. Like what, 36.0dBm at 3GHz, as one of your advertizers describes as high power? Puleez. And "heavily amplified"? Is that a useful term? Well, mabye if you're a rock band. I guess I'm expecting a little too much from this magazine. Plonk.
