Hi,
I'm searching a replacement to the ZC800 varactor with the following caps specs: 2v ===> 10pf
20v ===> 1.8pfIt's to equip a 350 ~ 500Mhz VCO (0v ~ 9v)
I've tried a BB405B but its capacity is too high at 9volt the maximum driving voltage at its upper frequency so the max frequency is 460Mhz, not
500.Many thanks for your help. pf
