Abstract : A discussion is presented of several of the items of equipment necessary in a radio frequency compatibility accessory equipment set. Major items discussed are the frequency measurement system and a standard response indicator for both CW and pulse systems. The specifications for other accessory items such as directional couplers, isolators, attenuators, dummy loads, and filters are also reviewed. Experimental work on the deposition of thin film alloys to obtain a film with a temperature coefficient of resistance which exhibits a minimum change of resistance over the temperature range of interest was conducted. Results of this work are shown. A receiver input coupler which provides for coupling from 50 to 300 ohm transmission systems was designed and its characteristics are shown. The problems associated with the audio susceptibility tester are discussed. Results of the evaluation of a rejection filter operating in the frequency range 100 to 400 Mc are presented.
