Hello genius Homies

i wanted to make a 500MHz or 1GHz sinusoidal Oscillator, i just need to know the easiest way to make one, i looked up the IC MAX038 & it's really Cool, but is there another one that would work at 500MHz or 1GHz? or do i have to look for a 1GHz Crystal Oscillator( idk if such thing exists )?

Please go easy on me, for i'm a Real Electronic noob , thanks.

 

Hello,

As far as I know, there are no chips that will cover the full 500 to 1000 Mhz.
Mini-Circuits makes VCO's that will cover about half the range.
To cover the whole range you will need two of these VCO's.
The POS 785 will go from 485 to 765 Mhz and
the POS 1060 will go from 750 to 1060 Mhz.
I have attached the datasheets.

Minicircuits makes a VCO that spans 400MHz to 1.2GHz that has coaxial SMA connectors.
Datasheet: http://www.minicircuits.com/pdfs/ZX95-1300+.pdf
At ~$50/ea, they're a bargain.

You will be very hard-pressed to build something yourself in that frequency range.

The MAX038 was discontinued long ago due to the unfortunate destruction of the factory due to natural causes. It was rated for up to 20MHz operation.

I don't know what a "n00b" would want with a sinewave generator with that high of a frequency capability. The test equipment to measure in that frequency range would cost a very tidy sum, even on the used equipment market. You would need a spectrum analyzer and an attenuator; even a used one might run in excess of $5,000.

 

It could probbly be done with one of Maxim's 2.5 GHz op amps

 

You are really helpful people, i'm already learning a lot from this forum, really Thank you all
