Fig. 7 — Explosed view of millimeter-wave converter. 



With the converter fixed-tuned at 5.4 millimeters, a shift in wave- 

 length to 6.3 millimeters (17 per cent change) produces a mismatch loss 

 of from 1.6 to 4.0 db depending on the rectifier used. 



PERFORMANCE DATA FOR WAFER-TYPE RECTIFIER UNIT 



A pilot group of one hundred wafer units was processed and measured. 

 Figs. 8, 9 and 10 are bar graphs of the distribution of the conversion loss 

 L, and noise ratio A^r*, and the 60 megacycle intermediate frequency 

 output impedance Zip , for the hundred rectifiers measured in the 



* Nu is the ratio of the noise power available from the rectifier to the noise 

 power available from an equivalent resistor at room temperature.
