Thank you for valuable reply on short notice
I am using WB2010 boards but Vtune for crystek VCO is limited to 5V max and max operating current is 20mA.
Pin-out is same.
VCO range is 925-970 MHz , but my end application is just gsm jammer, if I jam only the downlink frequency i.e. 935-960 MHz, will it work?
