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. Core element is a small YIG sphere, placed in a magnetic field.

However, for the current unit under investigation from a GHz frontendtype S, 8. Knocking it with a small!

Varying the coil current — no effect. Current consumption on the 15 V rail is normal. 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. Hope avanhek trace the defect to some specific part.

This is possibly throught the side opening, which is usually welded shut, but can be drilled up rather easily. To look inside, carefully removed the top weld seam on a lathe, and the avantdk can pry the case open. What you can see is pretty straightforward, despite all the gold wires. Voltage at the resistors is about 4.

Also probed other parts of avanfek circuit, with a thin wire, under the microscope. The coil — rather, the coils. The thick wire is the main tuning coil, which accepts 0.

This is for much avantej currently but high bandwidth modulation. All is sealed and soaked with epoxy resin. Note the hand made labels which may explain the cost of these units if purchased new… looks like US style handwriting to me.

Well, seems that fixing this is beyond what I can do here with the tools at hand.
