The power-saturated resonance absorption of a gas has been used to achieve mm-wave amplification. Experiments were conducted at room temperature in both a traveling wave system and in a resonant cavity. The results are in good agreement with theory. A gain of 20 dB was obtained with a 6 inch long, 34 inch-diameter cylindrical cavity at 86 Gc. A theoretical analysis indicates that the inherent noise figure of this device is 7 dB. Experimental noise measurements, which were limited by the sensitivity of the available test equipment, yielded an upper value of 25 dB for the noise figure. Author
