None of the oscillators have their pins.

The lower edge of the specified range 7. This is for much lower currently but high bandwidth modulation. This yug possibly throught the side opening, which is usually welded shut, but can be drilled up rather easily. With the specs determined, I now have enough information to continue work on my project using this oscillator. The analyzer allowed me to see the frequency move around as I changed the current on the tuning port.
Well, seems that fixing this is beyond what I can do here with the tools at hand. Satisfied that the module would behave somewhat as expected, I hooked it up to a spectrum analyzer.

Before verifying the suspected power level, I used an inline attenuator to avoid any chance of damaging the machine.
With a little investigating, it wasn’t very difficult to determine the approximate specs for the module I purchased. The particular oscillator I received is marked with model number SO and is labelled for 7.
To look inside, carefully removed the top weld seam on a lathe, and the you can pry the case open. This site uses Akismet to reduce spam. Core element is a small YIG sphere, placed in a magnetic field.
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 new posts avanrek email. It matches the first pinout in this old spec sheet. The closest standard units appear to be the AV through AV, which cover 8 to Then, join our amazing community.
There are also tons of Avantek ykg, in their standard round format, but a lot of them are custom part numbers with no avzntek known. This makes the module’s tuning behavior more like the next lower range, for example the AV Next, I measured the coil resistances. Also probed other parts of the circuit, with a thin wire, under the microscope. To determine the likely power output, I hooked the oscillator into a dummy load, then measured the current draw on the 15V input — it avantfk almost exactly mA, which means it is probably a 30 mW Learn more about dogecoin here.
Knocking it with a small!

At the upper end of 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. Power levels seemed to vary between 7 and 13 dBm across a wide range, however the analyzer calibration may be off somewhat.
Voltage at the resistors is about 4. The thick wire is the main tuning coil, which accepts 0.

Mystery YIG Oscillator – Doogie’s Blog
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.
The coil — rather, the coils. SimonsDialogs — A wild collection of random thoughts, observations and learnings. Facebook Twitter Reddit Email Print. 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. These do require a good amount of power, magnetic coils, etc, but provide stable and rather low noise output, and good modulation capability. Hope to trace the defect to some specific part. Varying the coil current — no effect.
Note the hand made labels which may explain the cost of these units if purchased new… looks like US style handwriting to me. What you can see is pretty straightforward, despite all the agantek wires.
