It's pretty basic stuff Guy. Look at what happens in this MRF150:
http://www.w8ji.com/demonstation.htm It would be nice if there was a free lunch and we could magically buy a device that didn't care about the load and gave reasonable operating efficiency and good IMD with any impedance from perfect to a 3:1 mismatch, but it isn't possible. Not blowing up in a few seconds on a data sheet test circuit is a whole lot different than being acceptable to operate that way in the real world. 73 Tom <<<<< Device web site was claiming "any angle" in the device specs. (!!!???) This should be fun to watch. 73, Guy.
