PERMEABLE-BASE TRANSISTOR.

Abstract

Permeable-base transitors, now in their infancy at MIT-Lincoln Laboratory, just may be one of two leaders in the next generation of transistors. While the other hopeful, the pseudomorphic HEMT, will probably serve low-noise millimeter-wave applications, the PBT will fulfill needs in high-power applications at microwaves and millimeter waves. The PBT's particular strengths seem to indicate that the PBT may be the device of choice for high-power MIMICs.
