DIGITAL RADIO FREQUENCY TRANSMITTER AND WIRELESS COMMUNICATION DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18151711 titled 'DIGITAL RADIO FREQUENCY TRANSMITTER AND WIRELESS COMMUNICATION DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a digital radio frequency (RF) transmitter that generates pattern signals based on binary data pairs and uses a switched-capacitor digital-to-analog converter (SC-DAC) to remove harmonic components from the RF analog signal.
- The transmitter generates three pattern signals based on a pattern of binary data pairs.
- The pattern signals have the same pattern but different phases.
- The SC-DAC amplifies the pattern signals to a certain magnitude ratio.
- The amplified pattern signals are synthesized into the RF analog signal.
- The SC-DAC removes the n-th harmonic component of the RF analog signal, where "n" is an integer of at least 3.
Potential Applications
- Wireless communication systems
- RF transmitters in mobile devices
- Satellite communication systems
Problems Solved
- Reduction of harmonic components in RF analog signals
- Improved signal quality and efficiency in RF transmission
Benefits
- Higher quality RF transmission with reduced harmonic distortion
- Improved efficiency in RF signal generation
- Enhanced performance of wireless communication systems
Original Abstract Submitted
A digital radio frequency (RF) transmitter including processing circuitry configured to generate first through third pattern signals based on a pattern of an inphase (I)-quadrature (Q) binary data pair and a pattern of an inverted I-Q binary data pair, the first through third pattern signals having a same pattern and different phases, and a switched-capacitor digital-to-analog converter (SC-DAC) configured to remove an n-th harmonic component of an RF analog signal by amplifying the first through third pattern signals to have a certain magnitude ratio and synthesizing the amplified first through third pattern signals into the RF analog signal, where “n” is an integer of at least 3, may be provided.
