1Productivity
If wired transmission lines (USB, HDMI) are used for data transmission between electronic consumer products, then hardware connection and stable transmission are achieved, but transmission bandwidth is limited and data transmission rate is restricted
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic field-based transmission system. The transmitter converts digital signals to RF signals that propagate through air space, eliminating physical connectors and cables. This substitution enables higher data transmission rates while removing hardware connection constraints.
Solution Approach 2:
The patent utilizes the 60 GHz frequency band with wide bandwidth parameters to achieve high-speed wireless transmission. By operating at this specific frequency range and utilizing available spectral resources, the system achieves data transmission rates significantly higher than conventional wired interfaces, while maintaining stable communication through appropriate modulation and signal processing techniques.
2Speed
If conventional wired transmission methods are used, then hardware stability is maintained, but transmission bandwidth is narrow and data transmission speed is limited
Solution Approach 1:
The patent integrates the transmitter and receiver into a complete wireless transceiving system that operates autonomously. The transmitter combines signal modulation, RF generation, and transmission functions in one unit, while the receiver integrates signal reception, demodulation, and data recovery functions. This merging approach achieves high-speed wireless transmission without requiring complex external hardware infrastructure.

AI summary
A differential radio frequency signal transmitter is provided. The differential radio frequency signal transmitter includes an oscillator, a modulator and an amplifier module. The oscillator generates a pair of differential oscillation signals. The modulator generates a pair of differential modulated signals according to an input signal and the pair of differential oscillation signals. The input signal is a digital signal. When the input signal is at a first state, the modulator outputs the pair of differential oscillation signals as the pair of differential modulated signals, and when the input signal is at a second state, the modulator outputs a constant voltage signal as the pair of differential modulated signals. The amplifier module receives and amplifies the pair of differential modulated signals and generates a pair of differential radio frequency signals, accordingly.
