Hi

I am looking for a Sine generator module with frequency range of 30MHz to 100MHz with phase noise better than -135dBc/Hz @ 1kHz offset.
Also i like that this module can work stand alone.
Are there someone know some manufacturers?

Regards
 

What is a "module"? How about an benchtop RF signal generator from someplace like Agilent?
 

Hi

I want to feed this signal to a sampling card and did not need a big signal generator.

Thanks
 

Use DDS( direct digital synthesis) chips from AD
 

HI

Use MIni-circuit VCO module - low cost sin wave out o dbm to + 10 dbm out out power



All the best

Hi

I am looking for a product. i do not want to design it myself.

Regards
 

Hi
The mini circuit VCO is a working module no need to design any thing al you have to do is to connect power {5V,12V etc} and signal output


All the best

Hi

I think that a VCO for stable operation need to be used with PLL, loop filter, ....
Am i right?
 

Hi

That depand how stable you need your signal to be ?

For instance you can stebilze the VCO with a good voltage regulator only

or Add PLL circuitry

Remember that you asked for simple solution

There are also PLL module who can generate high stable signal but are far more expensive in cost {+300~4000 $)

All the best

Hi

I want to apply that sine wave to a Mixed-Mode Board as clock, so i want a very pure and stable sine wave.

Regards
 

Hi

In orther to use it as clock signal for digital circuit you will need to convert the signal level into digital levels using ECL to TTL level converter.

Go to ON semi site there you will find ECL to TTL converter IC

Hi

The board i have used get a sine wave and convert it to PECL internaly, so i need only a pure sine wave :roll: :roll: :roll: :roll: :roll:
 

hi circuit seller,

I would say that it's difficult to find a cheap 'module' that can achieve -135dB phase noise. Most VCO circuit can only work within scale of 2: the highest freq cant beyond 2 times of the low freq. 30-100MHz needs band switchable circuit. and the output filter must also be switchable.

Maybe a wave generator is really a nice choice

you can buy a appropriate dds chip from analog device,

perhaps it can meet your needs.
