hello,
i try to put two jfets back to back and to block
ac signal between 0-10 voltage peak to peak
when i tried to input in Vgs a 4volt dc signal i could block just till 8 peak to peak
signal bigger then that started to pass throw
is it possible to block 10p-p with 4v dc?
is it connected to some requirment for Vgd?
should i chose a jfet with high or low Vpinch off?
should i use N-type for being able to work till 25 Mhz without falling in amplitude?
are there some types could be suggested
thanks forward
