6G / 5G Communications systems
The graph of SNR showing the effect of low noise and high gain offers big advantages in 6G communications:
Reduced communications channel bandwidth for a given data rate.
Better Spectral Efficiency for greater overall capacity.
Greater capacity for a 6G / 5G channel (for a given bandwidth)
Minimum radiation field for a given geographical coverage
RF amplifiers and detectors giving very low noise (without cryogenic cooling), and good high-frequency performance.
RF Mixers (reduced side-bands)
Medical
Medical imaging
Analog Amplifiers
Medical neuro-prosthesis (Implantable)
Designer circuit functions
Phase Locked Loop with very low phase noise.
Precision stable oscillators.
Analog/Digital & Digital/Analog conversion (e.g. ADC for 6G/5G).
RF Detectors
Current mirrors
Audio Analog/Analog to Digital CODEC (The reduction of shot-noise).
Video CODECS for video processing.
