Did it ever happen to you that you had a bag
filled with GaAsfets and you didnot know of which type these were,
or maybe you use Fets from old LNB or surplus, here is (maybe) the
solution for your problems......

I received an email which I include below FYI (Thanks David!)
I was looking some informations about GaAs Fet markings and
I find differences between your NEC chart and my databook.
Perhaps you're right or there is a unknown reason for such differences.
D=NE32584C
K=NE42484C
L=NE32984D
T=NE32484A
W=NE42484A
C,V,Y seems to be wrong too but I have not the PDF file for them at this
moment...
73's from F1URI, David
