ON-CHIP NETWORK ANALYZER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17448543 titled 'ON-CHIP NETWORK ANALYZER
Simplified Explanation
The abstract describes an integrated circuit that can measure the impedance presented to a transmitter path. It includes a directional coupler, a power amplifier, a power detector, a reference signal generator, and a vector modulator.
- The integrated circuit has a directional coupler with different ports for input, through, coupled, and isolation.
- It includes a power amplifier that is connected to the input port of the directional coupler.
- A power detector is used to measure the output levels from the coupled and isolation ports of the directional coupler.
- A reference signal generator is connected to the isolation port of the directional coupler.
- A vector modulator is used to adjust the phase of the signal generated by the power amplifier.
Potential applications of this technology:
- Wireless communication systems
- Radar systems
- Satellite communication systems
- Radio frequency (RF) testing and measurement equipment
Problems solved by this technology:
- Accurate measurement of impedance presented to a transmitter path
- Efficient power amplification and modulation
- Precise adjustment of phase in the signal generation process
Benefits of this technology:
- Improved performance and reliability of wireless communication systems
- Enhanced accuracy in impedance measurement
