Double-barrier quantum-well GaAs diode achieved 0.61 percent efficiency as frequency tripler when operated at input frequency of 63.7 GHz, nearly one-tenth cutoff frequency of diode. Efficiency increased with drive level up to maximum input power available, 40 mW. Diodes studied for use in local-oscillator chains in microwave radiometers. Potential applications include spectrometers and radar.
