Multiquantum‐well structures can be applied to the high‐frequency IMPATT oscillators. The first CW operation of GaAs/AlGaAs multiquantum‐well IMPATT oscillators at 100 GHz is reported here. Preliminary results yielded 6.4‐mW CW power at 100.3 GHz in a nonoptimized circuit. Significantly higher powers are anticipated with further optimization of the circuit parameters. The modern epitaxial technology opens up a new field for two‐terminal high‐frequency sources. © 1995 John Wiley & Sons, Inc.
