An investigation of wide-band nonregenerative decimeter and centimeter band parametric converters
Abstract
The noise and band characteristics of nonregenerative parametric up-converters (used in radio astronomy) are analyzed. A computer model is used to examine the passband widening of the converter, and test converters (in the 8 and 18 cm ranges) were found to have a relative passband close to that computed (about 40%).
