Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a circuit supporting 5G is designed in a similar manner to that of 3G and 4G, then the communication unit can support multiple communication standards, but the circuit configuration becomes more complicated and more components are required
Solution Approach 1:
The patent applies universality by enabling a single circuit configuration to perform multiple functions across different communication standards (3G, 4G, and 5G). The baseband processing unit and RF circuitry are designed to handle multiple standards without requiring separate dedicated circuits for each standard, thereby reducing overall device complexity while maintaining multi-standard support capability
2Adaptability or versatility
If a circuit supporting 5G is designed in a similar manner to that of 3G and 4G, then the communication unit can support multiple communication standards, but more components are required
Solution Approach 1:
The patent merges previously separate components into integrated units. The baseband processing unit is integrated to handle multiple standards, and the RF circuitry combines transmit and receive functions along with filtering and amplification in a unified architecture. This merging reduces the total number of discrete components required while maintaining support for 3G, 4G, and 5G communication standards

AI summary
A communication unit includes the following elements. A first transmit circuit outputs a first signal or a second signal from a first input signal. A first amplifier amplifies the first signal and outputs a first amplified signal. A first signal generating circuit generates a third signal having a frequency higher than a frequency of the second signal, based on the second signal and a first reference signal. A first filter circuit receives the third signal and allows one of a frequency component representing a sum of the frequency of the second signal and a frequency of the first reference signal and a frequency component representing a difference therebetween to pass through the first filter circuit and attenuates the other one of the frequency components. A second amplifier amplifies the third signal output from the first filter circuit and outputs a second amplified signal.
