RF Device Calibration via Pre-Assembly Component Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for calibrating radio frequency (RF) devices are inefficient as they require assembling all RF elements and multiplexers before calibration, consuming significant time and resources.
Innovation Solution
A method that involves obtaining measurement results for RF elements and multiplexers before assembly, determining estimated results by combining these measurements, and performing calibration operations post-assembly to improve calibration efficiency and reduce time consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all RF elements and multiplexers are assembled into the complete RF device before calibration, then the calibration can be performed on the full system, but the calibration process consumes a lot of time and is inefficient
Solution Approach 1:
The patent applies preliminary action by measuring and recording calibration data for individual RF elements and multiplexers before they are assembled into the complete RF device. This pre-measurement allows the calibration information to be stored and later applied during or after assembly, eliminating the need to wait until the entire device is assembled before beginning calibration. The calibration parameters are prepared in advance for each component, then combined to form the overall calibration profile for the complete system.
2Manufacturing precision
If calibration is performed on the complete assembled RF device, then all system interactions are accounted for, but the process is time-consuming and inefficient
Solution Approach 1:
The patent applies segmentation by dividing the calibration process into separate, independent measurements for each RF element and multiplexer before assembly. Each component is measured and calibrated individually, with its calibration data stored separately. This segmented approach allows for precise calibration of each element without requiring the entire system to be assembled, and the individual calibration results are later combined to achieve system-level precision while significantly improving overall calibration efficiency.

AI summary
An embodiment of the invention provides a radio frequency (RF) device calibration method. The method includes: obtaining a measurement result of a channel of a first-stage device under a control condition; obtaining a reference measurement result of a reference channel of a second-stage device, wherein the channel corresponds to the reference channel, and the measurement result and the reference measurement result are measured before the first-stage device and the second-stage device are assembled into an RF device; determining an estimated measurement result corresponding to the channel based on the measurement result and the reference measurement result; obtaining a post-assembly measurement result of the channel of the RF device under the control condition after the first-stage device and the second-stage device are assembled into the RF device; and performing a calibration operation corresponding to the channel based on the estimated measurement result and the post-assembly measurement result.
