Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external couplers and complex electronic circuits are used in conventional radar transceiver chips, then signal transmission and reception functions are achieved, but manufacturing complexity increases and reliability decreases
Solution Approach 1:
The patent integrates the coupler directly into the radar transceiver chip, merging previously separate external components (transmitting branch, receiving branch, and coupler) into a single integrated device. This eliminates the need for external couplers and complex electronic circuits, thereby reducing manufacturing complexity and improving reliability while maintaining signal transmission and reception functions.
2Ease of manufacture
If external couplers are used in conventional radar transceiver chips, then signal coupling is achieved, but manufacturing outlay and mechanical tolerances increase
Solution Approach 1:
By integrating the coupler onto the chip substrate rather than using external couplers, the patent eliminates the need for precise mechanical assemblies and external component mounting. This integration significantly reduces manufacturing outlay and relaxes mechanical tolerance requirements, making the manufacturing process easier and more cost-effective.
3Reliability
If multiple antenna terminals are used, then signal transmission and reception are achieved, but near-field behavior and high-frequency performance deteriorate
Solution Approach 1:
The patent uses a single antenna terminal that is coupled to both the transmitting branch and receiving branch through the integrated coupler. This merging of functions into a single terminal improves near-field behavior and high-frequency performance by minimizing spatial transfer paths, while the integrated coupler ensures proper signal separation and combination, thereby enhancing robustness without increasing device complexity.

Function Achieved in This Case
This configuration enhances the reliability and robustness of the radar transceiver chip by simplifying circuit complexity, reducing manufacturing outlay, and improving near-field behavior, while allowing for accurate filling level measurements in high-frequency applications.
Implementation Method 1
a coupler, by means of which the transmitting branch is coupled to the receiving branch and/or which couples the transmitting branch to the receiving branch
Implementation Method 2
the receiving branch comprises a receiving mixer which is configured to generate an intermediate frequency signal on the basis of the received signal
Implementation Method 3
A portion of the transmission signal can be reflected at the surface of the medium and fed into the receiving branch, as the received signal, via the antenna, the antenna terminal and/or the coupler
Implementation Method 4
The distance between the filling level measurement device and the surface of the medium and/or the filling level of the medium can thus be ascertained on the basis of a propagation delay method

AI summary
A radar transceiver chip for transmitting a transmission signal and for receiving a received signal is proposed. The radar transceiver chip includes a transmitting branch, a receiving branch, a coupler, by means of which the transmitting branch is coupled to the receiving branch, and exactly one antenna terminal for connecting an external antenna to the radar transceiver chip. The coupler is coupled to the antenna terminal and is configured to output at least a portion of the transmission signal to the antenna terminal and to feed at least a portion of the received signal, received via the antenna terminal, into the receiving branch, the receiving branch comprising a receiving mixer which is configured to generate an intermediate frequency signal on the basis of the received signal.
