Bottom line: I agree that Chip Angle GaAsFETs are the best. I even have one installed as a key element in a $300,000 submillimeter-wave test system at work. Like anything else that's man-made, as I found out, they are not infallible.
<----His newer designs are PHEMT too. In my numerous conversations with Chip, he's always maintained that his preamps may not provide the absolute last dB of gain but they are "unconditionally stable".
Of course I'd have to assume this means if it's operating properly! He does have network plots and other bit if useful info on his preamps here: http://www.anglelinear.com/gaasfet/gaasfet.html Ken ------------------------------------------------------------------------------ President and CTO - Arcom Communications Makers of the world famous RC210 Repeater Controller and accessories. http://www.arcomcontrollers.com/ Authorized Dealers for Kenwood and Telewave and we offer complete repeater packages!
