Radio-Over-Fibre TRIZ Cases
- Vector Decomposition Using Outphasing Signals for Low-Power Remote Units
Phase-rotated outphasing signals replace ADC and DAC functions in remote units, cutting power use and simplifying optical radio transmission.
- DOCSIS-MoCA coupled line directional coupler
Variable coupling length and resistor termination balance DOCSIS-MoCA isolation, insertion loss, and noise ingress in hybrid cable networks.
- Photonic ADC Phase Encoding for High-Dynamic-Range RF Signals
Optical phase encoding and calibrated noise cancellation let this photonic ADC digitize high-power RF signals across a wider dynamic range.
- Photonic ADC Optical Hybrid for High-Power RF Digitization
An optical hybrid and EO phase modulation let this ADC capture high-power RF signals across a wide dynamic range while avoiding transistor damage.
