YIG Oscillator

These do require a good amount of power, magnetic coils, etc, but provide stable and rather low noise output, and good modulation capability. The coil — rather, the coils. Well, seems that fixing this is beyond what I avanek do here with the tools at hand. A range of 6 dB matches the units on the spec sheet, but a 7 dBm minimum power is below that of any of the comparable modules.

Knocking it with a small! This makes the module’s tuning behavior more like the next lower range, for example the AV Learn more about dogecoin here. Your email address will not be published. This site uses Akismet to reduce spam.

There are quite a few of the miniature Stellex units on eBay, but they generally don’t go much past 10 GHz. 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 thick wire is the main tuning coil, avanhek accepts 0. Leave a Reply Cancel reply Your email address will not be published. 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. Next, I measured the coil resistances.


As expected from this helpful documenta fair amount of tune current was required before oscillation started. Perhaps that was another thing that made this part a special order. What you can see is pretty straightforward, despite all the gold wires.

With mA flowing, a signal finally popped up at around 7. The lower edge of the specified range 7. Notify me of follow-up comments by email.

At the upper end of However, for the current unit under investigation from a GHz frontendtype S, 8. Voltage at the resistors is about 4. To determine the likely power output, I hooked the oscillator into a dummy load, then measured the current draw on the 15V input — it was almost exactly mA, which means it is probably a 30 mW Top Tags acer ahk antenna arduino basics capacitor car electroluminescent f-script fluke ford gti hack hardware iOS lumia mac microwave monitor moon mosfet mount mystery obd-ii oscillator osx phone plague repair satellite script serial software space utility vw windows yig.

SimonsDialogs — A wild collection of random thoughts, observations and learnings. With the specs determined, I now have enough information to continue work on my project using this oscillator.

Save my name, email, and website in this browser for the next time I comment. The analyzer allowed me to see the frequency move around as I changed the current on the tuning port. Power levels seemed to vary between 7 and 13 dBm across a wide range, however the analyzer calibration may be off somewhat.


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. Core element is a small YIG sphere, placed in a magnetic field. Varying the coil current — no effect.

Mystery YIG Oscillator

With a little investigating, it wasn’t very difficult to determine the approximate specs for the module I purchased. Satisfied that the module would behave somewhat as expected, I hooked it up to a spectrum analyzer.

Current consumption on the 15 V rail is normal. 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. Also probed other parts of the circuit, with avantem thin wire, under the microscope. Notify me of follow-up comments by email. All is sealed and soaked with epoxy resin.
