This is for much lower currently but high bandwidth modulation. Since this particular project wasn’t very sensitive to any of the parameters, I waited for a cheap one to show up with the right range and went for it. The particular oscillator I received is marked with model number SO and is labelled for 7. Sorry, your blog cannot share posts by email.

The coil — rather, the coils. For a project I am currently working on, which I will detail here too eventually, I needed an oscillator capable of covering 8 to 12 GHz. With mA flowing, a signal finally popped up at around 7.

Mystery YIG Oscillator

Also probed other parts of the circuit, with a thin wire, under the microscope. Your email address will not be published. Facebook Twitter Reddit Email Print. Satisfied that the module would behave somewhat as expected, I hooked it up to a spectrum analyzer. This makes the module’s tuning behavior more like the next lower range, for example the AV Core element is a small YIG sphere, placed in a magnetic field.


All is sealed and soaked with epoxy resin. Current consumption on the 15 V rail is normal. SimonsDialogs — A wild collection of random thoughts, observations and learnings. The analyzer allowed me to see the frequency move around as I iyg the current on the iyg port. With avantk specs determined, I now have enough information to continue work on my project using this oscillator. Learn more about dogecoin here. To look inside, carefully removed the top weld seam on a lathe, and the you can pry the case open.

There are also tons of Avantek modules, in their standard round format, but a lot of them are custom part numbers with no specifications known. Next, I measured the coil resistances. Learn how your comment data is processed. Hope to trace the defect to some specific part. Acantek the coil current — no effect.

Before verifying the suspected power level, Yg used an inline attenuator to avoid any chance of damaging the machine. Knocking it with a small!

A19 board, YTO unlock, bad precision trimmer s. It matches the first pinout in this old spec sheet. Well, with all the basics checked, what to do with such hermetically sealed unit, other than using it to satisfy my curiosity about its internals. Notify me of follow-up comments by email.


This is possibly throught the side opening, which is usually welded shut, but can be drilled up rather easily. These do require a good amount of power, magnetic abantek, etc, but provide stable and rather low noise output, and good modulation capability. Note the hand made labels which may explain the cost of these units if purchased new… looks like US style handwriting to me.

The closest standard units appear to be the AV through AV, which cover 8 to Then, join our amazing community. Notify me of follow-up comments by email. Save my name, email, and website in this browser for the next time I comment. However, for the current unit under investigation from a GHz frontendtype S, 8. Perhaps that was another thing that made this part a special order.

What you can see is pretty straightforward, despite all the gold wires. The thick wire is the main tuning coil, which accepts 0. This site uses Akismet to reduce spam. Leave a Reply Cancel reply Avzntek email address will not be published.
