Abstract :
47-GHz monolithic microwave integrated circuit (MMIC) power amplifier chips have been developed using 0.35-mm gate-length molecular beam epitaxial (MBE) MESFET technology. The amplifier chips have been assembled with nominal output power of 0.4 W and 15 dB of gain. The saturated output power of this amplifier exceeded 0.5 W. This amplifier has an application as a driver for a monolithic doubler circuit to reliably produce greater than 80 mW of output power at 94 GHz for missile seeker applications.<>
