TUNABLE HIGH-LINEARITY LOW NOISE AMPLIFIER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240291440 titled 'TUNABLE HIGH-LINEARITY LOW NOISE AMPLIFIER
Simplified Explanation: The patent application describes an amplifier that can operate in multiple modes to handle different types of signals and optimize performance.
Key Features and Innovation:
- The amplifier has a default mode for high gain and power-saving when no out-of-band blocker signals are present.
- It can switch to a Long Term Evolution (LTE) blocking mode for dealing with blockers during LTE operation.
- The amplifier also has a Global System for Mobile (GSM) blocking mode with high compression point for GSM operation.
- A protection mode is activated when the voltage of a received signal is excessive to safeguard the amplifier or the device it is in.
Potential Applications: The technology can be used in various communication devices such as radios, transceivers, and other wireless devices that require signal amplification and protection.
Problems Solved: The amplifier addresses issues related to signal interference, power consumption, and signal protection in different operational scenarios.
Benefits:
- Improved signal amplification performance
- Enhanced protection against excessive voltage
- Efficient power management in different signal environments
Commercial Applications: This technology can be applied in the telecommunications industry for the development of advanced amplification systems in mobile phones, base stations, and other wireless communication devices.
Questions about the Technology: 1. How does the amplifier determine which mode to operate in? 2. What are the specific criteria for switching between different modes?
Frequently Updated Research: Ongoing research in this field focuses on enhancing the efficiency and adaptability of amplifiers in various signal environments.
Original Abstract Submitted
an amplifier (e.g., a low noise amplifier (lna)) may operate in multiple modes, including a first, default mode (e.g., a high gain and/or power-saving mode) which may apply when an out-of-band blocker signal (e.g., transmitted or received by other radios, transceivers, or devices) is not present. the lna may also operate in a second, long term evolution (lte) blocking or high linearity mode, which may be selected when a blocker and/or transmission signal leakage is present during, for example, lte operation. the lna may further operate in a third, global system for mobile (gsm) blocking mode, which may include a high compression point to withstand a gsm blocker that may be present during, for example, gsm operation. the lna may also operate in a protection mode when voltage of a received signal is excessive to protect the lna or device having the lna.
