DUPLEXER MEASUREMENT AND TUNING SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240080063 titled 'DUPLEXER MEASUREMENT AND TUNING SYSTEMS

Simplified Explanation

The patent application describes systems and methods for combining a test signal with a wanted signal at the input of a duplexer in a communication device, and then measuring the power difference between the test signal at the output of the duplexer and the input. The tuning state of the duplexer is adjusted based on this measurement to optimize performance.

• Test signal combined with wanted signal at duplexer input
• Test signal may be RF signal with less power or digital signal
• Processor causes duplexer to operate in tuning state
• Measurement system determines power difference and adjusts tuning state

Potential Applications

• Wireless communication devices
• Radio frequency testing equipment
• Signal processing systems

Problems Solved

• Interference between test signal and wanted signal
• Optimization of duplexer performance
• Efficient tuning of communication devices

Benefits

• Improved signal quality
• Enhanced performance of communication devices
• Simplified testing procedures

Possible Prior Art

There may be prior art related to the optimization of duplexer performance in communication devices, but specific examples are not provided in the patent application.

Unanswered Questions

How does the tuning state adjustment impact the overall performance of the communication device?

The patent application describes adjusting the tuning state of the duplexer based on the power difference measurement, but it does not delve into the specific effects of this adjustment on the device's performance.

Are there any limitations to the types of test signals that can be combined with the wanted signal in this system?

The patent application mentions using test signals with less power or digital signals, but it does not address whether there are any restrictions on the characteristics of these test signals.

Original Abstract Submitted

systems and methods combine a test signal with a wanted (downlink or uplink) signal at an input of a duplexer of a communication device, and receive the test signal at an output of the duplexer. the test signal may include a radio frequency signal having less power than the wanted signal to avoid interference, or a digital signal that is added to or extracted from the wanted signal when the wanted signal does not have a radio frequency. a processor of the communication device causes the duplexer to operate in a tuning state (e.g., to transmit signals having a transmission frequency and receive signals having a receive frequency). the measurement system determines a difference or ratio in power between the test signal at the duplexer output and the duplexer input, and adjusts the tuning state based on the difference or ratio (e.g., to decrease or minimize the difference or ratio).
