VCO for GPS application

I have some problems with designing a VCO for GPS application.I am new to VCO design so I don't know how to determine the exact amplitude and phase noise of the VCO.who can help me ?
 

Re: VCO for GPS application

The amplitude is going to depend on the signal level that the mixer it's feeding requires. The phase noise specification is also going to depend on the Mixer output frequency.
