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

To look inside, carefully removed the top weld seam on a lathe, and the you can pry the case open. Learn how your comment data is processed.

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. With the specs determined, I now have enough information to continue work on my project using this oscillator.

Voltage at the resistors is about 4. A19 board, YTO unlock, bad precision trimmer s. This is for much lower currently but high bandwidth modulation. Next, I measured the coil resistances.

The lower edge of the specified range 7.

Notify me of new posts by email. With mA flowing, a signal finally popped up at around 7.

Also probed other parts of the circuit, with a thin wire, under the microscope. Hope to trace the defect to some specific part. Perhaps that was another thing that made this part a special order.

Your email address will not be published. It matches the first pinout in this old spec sheet. Satisfied that the module would behave avante as expected, I hooked it up to a spectrum analyzer.

The thick wire is the main tuning coil, which accepts 0.

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 avxntek modules. As expected from this helpful documenta fair amount of tune current was required before oscillation started. Leave a Reply Cancel reply Your email address will not be published.

Varying the coil current — no effect. Facebook Twitter Reddit Email Print. SimonsDialogs — A wild collection of random thoughts, observations and learnings. However, for the current unit under investigation from a GHz frontendtype S, 8. Your email address will not be published.

The analyzer allowed me to see the frequency move around as I changed the current on the tuning port. Sorry, your blog cannot share posts by email. The closest standard units appear to be the AV through AV, which cover 8 to These do require a good amount of power, magnetic coils, etc, but provide stable and rather low noise output, and good modulation capability.

What you can see is pretty straightforward, despite all the gold wires. Then, join our amazing community. Well, seems that fixing this is beyond what I can do here with the tools at hand.
