Research abstract

This proposal describes an innovative approach to the objective of developing a large area portable antenna with support electronics including high power, wide bandgap, transistor amplifiers on very large flexible metal substrates. We believe that the refractory nature of wide bandgap semiconductors will also allow operation at very high temperatures if necessary. In addition, the very high breakdown field and saturated drift velocity of the wide bandgap material predict not only Fmax values exceeding 80 GHz but also high (1.0 -2.0 kV) operating voltages. Maximum Available Gains in excess of 18 dB at 10 GHz are predicted, along with Power Added Efficiencies of 45+ % (Class A operation) and 70+ % (Class B operation). Pulse power outputs of the order of 1 MW for a 1 usec pulse are expected.
