Facebook Twitter Reddit Email Print. 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 To look inside, carefully removed the top weld seam on a lathe, and the you can pry the case open.

This is for much lower currently but high bandwidth modulation. Learn more about dogecoin here. At the upper end of The particular oscillator I received is marked with model number SO and is labelled for 7. Next, I measured the coil resistances. For a project I am currently working on, which I will detail here too eventually, I needed an oscillator capable of covering 8 to avanteek GHz.


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.

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

Before verifying the suspected power level, I used an inline attenuator to avoid any chance of damaging the machine. 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. The closest standard units appear to be the AV through AV, which cover 8 to A19 board, YTO unlock, bad precision trimmer s. Your email address will not be published. Well, with all the basics checked, what to do with such hermetically avanetk unit, other than using it to satisfy my curiosity about its internals.

Sorry, your blog cannot share posts by email. Then, join our amazing community. With the specs determined, I now have enough information to continue work on my project using this oscillator. Note the hand made labels which may explain the cost of these units if purchased new… looks like US style handwriting to me. This makes the module’s tuning behavior more like the next lower range, for example the AV With a little investigating, it wasn’t uig difficult to determine the approximate specs for the module I purchased.


Current consumption on the 15 V rail is normal. Knocking it with a small! The thick wire is the main tuning coil, which accepts 0. Your email address will not be published. It matches the first pinout in this old spec sheet.

There are quite a few of the miniature Stellex units on eBay, but they generally don’t go much past 10 GHz.

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. Voltage at the resistors is avante 4.

All is sealed and soaked with epoxy resin. Also probed other parts of the circuit, with a thin wire, under the microscope.

Satisfied that the module would behave somewhat as expected, I hooked it up to a spectrum analyzer. As expected from this helpful document avangek, a fair amount of tune current was required before oscillation started.

Hope to trace the defect to some specific part. Learn how your comment data is processed. With mA flowing, a signal finally popped up at around 7.
