Spacecraft guidance, navigation and control based on application of resonant tunneling diodes in nonlinear radio signal converters

The prospects of application of resonant tunneling diodes (RTD) based on nanoscale AlAs/GaAs heterostructures in non-linear radio signal converters of spacecraft guidance, navigation and control systems are demonstrated. A diagnostic model of the RTD has been developed. It makes it possible to obtain the kinetics of RTD current-voltage characteristics and the indices of non-linear converters of SHF radio signals under the influence of destabilizing factors during operation. The experimental data of the RTD current-voltage characteristic kinetics under the influence of destabilizing factors are presented. © 2017 Univelt Inc. All rights reserved.
