a Vco for my ADF7021-V

Hi,

I am working with the ADF7021-V. I try to make a 140MHz transceiver.

I'm looking for a VCO, but i can't find a good one for this component.

 

I need a VCO for 276MHz to 310MHz if i don't use the  RF_DIVIDE_BY_2 register. or  552MHz to 620MHz if RF_DIVIDE_BY_2=1.

If I well understand the ADF7021-V can only tune the voltage control between 0.3V and 2V. But all VCO (I found) need at least a voltage tune between 0.5V and 5V.

 

Is there a way to solve this problem ?

Thanks

 

Cedric
