The lower edge of the specified range 7. This is for much lower currently but high bandwidth modulation. 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. Facebook Twitter Reddit Email Print.

Varying the coil current — no effect. 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. Current consumption on the 15 V rail is normal. This site uses Akismet to reduce spam.

With mA flowing, a signal finally popped up at around 7. At the upper end of Also probed other parts of the circuit, with a thin wire, under the microscope. Note the hand made labels which may explain the cost of these units if purchased new… looks like US style handwriting to me.

Voltage at the resistors is about 4. Notify me of follow-up comments by email. 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.

For a project I am currently working on, which I avanrek detail here too eventually, I needed an oscillator capable of covering 8 to 12 GHz. Next, I measured the coil resistances. Power levels seemed to vary between 7 and 13 dBm across a wide range, however the analyzer calibration may be off somewhat.

The closest standard units appear to be the AV through AV, which cover 8 to Notify me of follow-up comments by email. It matches the first pinout in this old spec sheet.

These do require a good amount of power, magnetic coils, etc, but provide stable and rather low noise output, and good modulation capability. As expected from this helpful documenta fair amount of avzntek current was required before oscillation started.

With the specs determined, I now avantei enough information to continue work on my project using this oscillator. There are quite a few of the miniature Stellex units on eBay, but they generally don’t go much past 10 GHz.

Perhaps that was another thing that made this part a special order.

This is possibly throught the side opening, abantek is usually welded shut, but can be drilled up rather easily. Save my name, email, and website in this browser for the next time I comment. The coil — rather, the coils.

To look inside, carefully removed the top weld seam on a lathe, and the you can pry the case open. Hope to trace the defect to some specific part. Well, seems that fixing this is beyond what I can do here with the tools at hand. Knocking it with a small! 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. SimonsDialogs — A wild yigg of random thoughts, observations and learnings.

What you can see is pretty straightforward, despite all the gold wires. Before verifying the suspected power level, I used an inline attenuator to avoid any chance of damaging the machine.

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 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.
