LO generation question

[bageduke]

Hi, guys,

I am working on VHF band receiver which is from 30MHz up to 300MHz. So far our existing VCO working range is from 1.8GHz to 3.4GHz. Is there good way we can use the current VCO to generate LO signal from 30MHz to 300MHz without adding another VCO or expanding VCO range?

Any thoughts is appreciated.

Thanks a lot.

ur VCO frequency is much higher than the required frequcmy , so use a frequancy divider , to get what u want
or try to buy a VCO more cheaper than u have , and cover ur band
