New approach to GaAs MESFET analog frequency dividers with low threshold input power and high conversion gain

Abstract

An approach to frequency dividers based on the nonlinear feedback control of MESFET in the forced oscillation mode is proposed. The input signal is used to control the MESFET gain, imposing oscillation conditions. A design of frequency dividers based on this approach which allows the threshold input power to be reduced and the conversion gain to be increased. is proposed. Frequency division is tested using time-domain simulation. and an X-band experimental MESFET analog frequency divider which exhibits a high conversion gain and a low threshold input power is discussed. >
