I want to make oscillator range from 500MHZ to 2GHZ?help me!

500mhz oscillator

I want to make oscillator range from 500MHZ to 2GHZ? which oscillator you suggest me???
Colpitts,Clapp or Hartley
and why you suggest this???
please tell me i need to know about it??

2ghz+oscillator

It is very difficult to realize an oscillator with 1.5 GHz bandwidth.
Colpitts or simular can be a good choiche, a common base bjt with the resonator in base...

can i do this with cascaded circuit??
like

o/p of 1st oscillator in i/p of second oscillator?

This is a Colpitts VCO example

 

[BigBoss]

I guess the differential VCO may be a good choice.But due to some restrictions like phase noise,temperature effects,pulling etc. this oscillator using with dicrete components can be a little bit sensitive for practical purposes..
But it's possible..

 

[bt87]

any VCO for range of
925-960 MHZ

 

[maheshkuruganti]

Try this its a 860Mhz - 950Mhz OSC with Integrated Tank Circuit. Its the MAXIM 2623

Added after 3 minutes:

Also Even I tried to do that Wideband VCO and from my experience I can tell you the best way is to take two Wideband VCOs and put them through a Mixer and filter the output. Else If you would rather have lesser work you could get a Mini Circuits Designer Kit KPOS1+ which has low phase noise Osc from 25Mhz to 1Ghz, they do have higher frequencies also like the 2GHz range.But mind you it is 13 VCOs
