Delaying/shifting the start of a square wave inverter

[artis]

By the way, how do I POWER RF systems? Is there anything that con hold a battery and use it to run an RF system? And is it adjustable?

Please take no offense but do you really understand what you are trying to do?

It's like asking "how do I drink a beer bottle" "do I hold it upside down and let the liquid flow into my mouth, can I adjust the flow of beer? "

I would really suggest explaining what you are doing fully and what you aim to do, that is the only way you will get a meaningful answer and maybe even learn something. In case you think you have a novel idea and are reluctant to share , I would suggest that cannot be the case given you ask such basic questions that show your lack of understanding in the field.

It no longer has to be a square wave.

As I understand it, you want a quadrature shifted wave so you can make a circulating field in a cavity at a frequency greater than 4 GHz.

You originally considered crossed coils with "iron" to make stronger fields, and RC phase shifters, but have now switched to capacitor plates with delay lines. Now you are suggesting a 1.6 GHz antenna will be operated at above 4 GHz.

It now looks like you need a cavity in a waveguide system that will support a circularly polarised wave. Then you can dispose of the quadrature shifter and the associated antenna losses. There can be little point in this thread if you will not identify what will go in the cavity and why that something will magically behave differently.

You have still not specified the power required to drive the magic.

That's only one of the things that have not actually been addressed by the OP. I think he has no idea of what he's actually proposing.

I foresee a cardboard box in the OP's shed / basement, full of (expensive) microwave bits that have never actually been connected up. This is not the way to approach a serious research project but suppliers are always happy to sell experimenters stuff that won't be of any use to them.

I really don't think this confirmation of the Dunning-Kruger effect will get as far as the cardboard box. Secrecy is essential in that it prevents a final design, so no experiment is possible. Any attempt to actually experiment will rapidly demonstrate failure, and so destroy the delusion. It must forever remain a dream.

Also I am going to use the 1.575GHz patch-type antenna for this.

You do know what that band is used for, right? What do you think will happen when you start throwing out sloppy versions of your signal in that band?

This thread has gone on long enough. We don't support newbies trying to design GHz transmitting circuits for secret applications. Thread is closed.
