Barrier Resistance The approximate operating value of the barrier resistance, /?, may bedetermined from a knowledge of the intermediate frequency impedanceof a typical rectifier. A. B. Cra^^^ord has sho-wn that the optimum inter-mediate frequency output impedance of a crystal mixer rectifier is afunction of the exponent of the static characteristic of the rectifier andthe impedance presented to the rectifier at the image and signal fre-quencies. This information is presented in Fig. in G. C. South-worths In the millimeter wave case it is a good assumption thatthe impedances for the signal and image frequencies ar
