Hi guys,

I was just wondering of there is any companies that manufactures a 1.7 Ghz oscillators ?

For the thing I need, I have a stable supply of voltage and I need a specfic frequencey, the one mentioned above. So a VCO, I think, is not the solution as some of you may suggest.

Please, if you now companies that do manufacture them I would greatly appreciate your help,


thanks

What is the application? What power level?

Well the output of the oscillator will be connected to a horn antenna, and from its characteristics, the least attenuation occurs at this frequencey.

I prefer that the oscillator have a wide range of inputs and produces a correspnding output, with the freq. unchanged.

If you want a specific value, then it would be 25 watts as an output.of the oscillator.

A typical scheme is to have an LO chain or a synthesizer, and then feed it to a power amp.

there is many manufactures making these for defense, and they are quite expensive, try googling. But on ebay, you many find oscillators that are not manufactured anymore for a fraction of the cost.

some of the manufactures I'm familiar with:

macom, herley, miteq or microsource.

I don't know if they are still making "microwave bricks" that you get for any frequency.

25 W is equal to 44 dBm, that is LOT of power for a microwave circuit. You can certainly buy power amplifiers that can do this (you can buy amplifiers meant for e.g. radar that will give you kW of power); but it is well outside what you can get out of a typical "lab" amplifer (they will typically give you 15 dBm at most).
Hence, an amplifer like this is likely to be quite expensive.
