The technique of millimeter wave amplification is extended to the one millimeter wave region of the spectrum. An amplifier was constructed and tested at a frequency of 258 GHz. This amplifier, operating in a room temperature environment, exhibited a gain of 20 db. The measured gain bandwidth product was 7 MHz. A measurement performed at 200 degree K predicts a three-fold increase of the gain bandwidth product at this temperature. The theory of the amplification phenomena was refined and a prior reported theoretical noise figure of 8 db should be reduced to 5 db for room temperature operation and to 3.3 db for operation at 200 degree K. A new technique for absolute power measurements at a frequency of 258 GHz was developed. This technique is based on the utilization of resonance absorption saturation and is sensitive down to one microwatt.
