Solution Overview

Problem

Current wireless transceivers are limited in their ability to efficiently operate across multiple frequency bands, such as 2.4 GHz, 5 GHz, and 6 GHz, as they often require separate configurations and amplification for each band, leading to increased noise figures and insertion losses.

Innovation Solution

A wireless transceiver design that includes multiple transmitter/receiver chains with amplifier circuits and switch elements, allowing for configuration across multiple frequency bands, such as 2.4 GHz, 5 GHz, and 6 GHz, with a multiplexing element to direct signals and filters to reduce noise and insertion loss, enabling simultaneous operation across different frequency bands.

Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines multiple frequency band signal paths into a shared amplifier circuit. The amplifier is positioned after the signal paths diverge from the antenna node, allowing a single amplifier to serve multiple frequency bands (2.4 GHz, 5 GHz, 6 GHz) simultaneously, thereby reducing the number of amplifiers needed and lowering overall noise figures and insertion losses while maintaining multi-band adaptability

Inventive Principle:

Solution Approach 2:

The amplifier circuit is designed as a universal component that can amplify signals across multiple frequency bands. By making the amplifier multi-functional rather than having separate amplifiers for each band, the system achieves efficient multi-frequency operation with reduced noise and insertion loss, as the same amplifier infrastructure serves multiple purposes

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate amplifier circuits are used for each frequency band, then each band can be optimized independently, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent merges the amplification function for multiple frequency bands into a single shared amplifier circuit. Instead of having separate amplifiers for 2.4 GHz, 5 GHz, and 6 GHz bands, one amplifier serves all bands, significantly reducing device complexity while still enabling optimized signal amplification across each frequency band through the shared infrastructure

Inventive Principle:
