Abstract : Quasioptical power combining allows the combining of a large number of devices in free space without the usual transmission line combiner losses. It is a particularly attractive idea at millimeter wavelengths, where the devices can be made as a monolithic integrated circuit. During this contract we demonstrated the following significant 'firsts': (1) Monolithic quasioptical millimeter wave oscillator - 35 GHz; (2) Quasioptical oscillator with significant power 10 W; (3) Large scale quasioptical amplifier - 200 devices; (4) Quasioptical amplifier with significant power-3.8 W; (5) Monolithic millimeter wave quasioptical amplifiers with gain 5 dB at 40 GHz and 50 GHz. The saturated output power of the 40-GHz amplifier is 400 mW.
