I have that information and I did reverse out the diagram portions I was interested in detailing, which are the different bias schemes for the different active devices.
I'll happily make that information available when I locate that buried folder. Today might be a day to slightly clean up the office paperwork stack. A friend and I are casually setting up to run models of both wide and narrow band RF Pre-amplifiers. The subject has already started an interesting email debate with another group of friends. The termination Z (impedance) actually seen by the preamplifier does affect the IMD. How much and where is what we hope to get a better look at. s. > Joe <k1ike_m...@...> wrote: > As far as I know, GLB never made the schematic > available. > I posted to the FILES area what I received with > the preamps that I had purchased over the years. > I've used them on all three bands with good > luck.
