vco output power and wiring?
Here is a dBm-volts-watts conversion table:
Conversion Table/Decibels-Volts-Watts
They're all over google in pdf or whatever.
ZX95-625A+ +6.2 dBM power output = 0.4mW @ 0.445 v (at 6.0 dBM)
ZX95-200-S+ +10 dBM power output = 10mW @ 0.71v
This patent won't do anyone any good but I'm just posting it because
it is the patent for these vco enclosures listed on the data sheet:
Mechanical case for housing ... - Google Patent Search
These modules have vcc, gnd and vtune.
Is there wiring diagram to power them? It isn't on the data sheet.
Does power like 6v battery simply get hooked to vcc and gnd and the
positive from the battery go through a variable pot to vtune or is it not
as simple as that?

A little advice
@All
Before rushing and buying anything, I advise that you buy the two VCO's as a 50ohm cable connection as these are very delicate to solder onto a board, also if you look at the output you will see that they are in the very low mW range and as so will have to have an amplification even before the power amplifier. This is not complicated but will have to be made, so you will have a two stage linear amplifier.
I have a dBm-volts-watts conversion table which will give the output voltage and wattage if anybody requires it.

I can't see why not.
If you go to view data it give you all the frequencies at different voltages.
I mailed their support department with some questions and will report back once I get an answer.

ZX95-200-S+ and ZX95-625A
Minicircuits.com has these modules for sale.
I can find the ZX95-625A+ but not just 625A.
Will it work anyway?
And the ZX95-200-S+, I can only find the ZX95-200+ and not 200-S+
Will that work anyway too?
(links above are for data sheets)

ZX95-200-S+ and ZX95-625A
I did start to build Dr. Stiffler's circuit in LTSpice IV. The program didn't evenOriginally posted by Duncan View PostMini-Circuits RF/IF Designer's Guide and UHF oscillator using Mini-Circuits' POS-400+ chip for consideration
have a transistor! Guess I have to download those and add them. In any
case, I made some progress with at least laying it partially out and selecting the
components but can see that it has an instruction manual for a reason.
But if I can do an easier job with this kind of circuit, I'd rather do that.
Like Dr. Stiffler said, nobody is going to build his the same. The Ainslie
circuit experiments is the closest I ever saw to open source standardization
and any hopes of getting anywhere near a "standard" for that circuit are
probably nil to none.
@Mike - have you found a source for these?
"The ZX95-200-S+ and ZX95-625A will give you the two frequencies you need and the bonus is they are variable through a wide range, total cost 87.90usd."
I only find a bunch of data sheets and most sites are overseas.

A very interesting article, but I do not think it has anything to do with this as a simple spray system creating a fine mist also works, although there is a significant increase of hydrogen and oxygen from vapour, I put this down to enhanced surface area of the water molecule, as has been shown under tests. All the same it is very very interesting.Originally posted by DrStiffler View Post

GOLD, interesting, might like to read thisOriginally posted by Michael John Nunnerley View PostI will try and answer your questions, first good ultrasonic transducers have a very thin coating of gold so as impurities do not eat away the transducer. Secound most of the RF is absorbed by the water at the frequencies we are talking about and the transducer is submerged below the water line. A fine spray system can be used instead, such as heated water "steam". Third, the breaking will form atomic H and O but will look to bond with another H or O and form H2 and O2 so the only gases you get out are those. Finally if air is in the system you will get no chemical bonding at this level, you will just get air mixed with the H2 and O2.
Maybe in the future I will explain how we can bond N2 with H2 and O2, but here in this thread it is down to basics of splitting water into H2 and O2, so please keep on track for doing this and building up the equipment required so as at least one person has a replication and I hope a lot more, lets learn to walk before we run, all will fall into place.

IMHO after a period of operation the cell will purge itself of atmospheric gases. Just how well will the cell function, can we expect to see atomic or diatomic hydrogen and oxygen. Can anyone speculate on the reactions that can occur if we were to reintroduce the atmospheric gases back into the cell.

YouTube - Sine Wave to Square Wave using Fourier SeriesOriginally posted by nvisser View PostIt seems like saw resonators are not the preferred choice. I also cannot find ones that has frequencies 6x exactly apart and they need to be used with a resonant circuit. They are dirt cheap though
It looks like the voltage controlled oscillators will be much easier.
K-POS 2+ kit consist of 7 kits which include POS200+ and POS765+ which will be the correct voltage controlled oscillators to use. Then we can use 100 and 600Mhz.Last edited by Duncan; 09-30-2010, 09:05 AM.

vco POS-100+ VOLTAGE CONT OSC / RoHS $16.95 1 IN STOCK $16.95
vco POS-765+ VOLTAGE CONT OSC / RoHS $19.95 1 IN STOCK $19.95
Total $36.90
These units are much cheaper. They look like pcb mount units unlike the ZX95-200-S+ and ZX95-625A that are loose items.
It seems like they are similar in function but this one has not got an output connector.Last edited by nvisser; 09-30-2010, 07:29 AM.
