Tunable Duplexer Using Dielectric Position Control Across Sub-Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing duplexers have non-adjustable operating frequencies, leading to poor flexibility and a narrow application range, requiring manufacturers to maintain a large inventory of spare parts for different frequency sub-bands.
Innovation Solution
A duplexer design incorporating a dielectric tuning component and a control module that adjusts the relative position between the dielectric tuning component and the filter to change the operating frequency, using a motor unit and control module to precisely control this position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the duplexer uses a fixed frequency design, then the manufacturing process is simple and reliable, but the adaptability and application range are limited
Solution Approach 1:
The patent applies the dynamics principle by making the dielectric tuning component movable rather than fixed. The component can be adjusted to different positions along the axial direction to change the resonant frequency of the duplexer, enabling it to adapt to different frequency bands while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent changes the physical parameter of the dielectric tuning component's position to adjust the operating frequency. By moving the dielectric component to different locations, the electrical characteristics of the duplexer change, allowing frequency adjustment without fundamentally changing the device structure.
2Adaptability or versatility
If the duplexer is designed for multiple frequency bands, then the application range expands, but the inventory management complexity increases
Solution Approach 1:
The patent makes a single duplexer device universal by enabling it to operate across multiple frequency bands through adjustment of the dielectric tuning component. This allows one device to perform multiple frequency functions, eliminating the need to maintain separate inventory for different frequency bands.
Solution Approach 2:
The adjustable dielectric tuning component enables the same hardware to dynamically adapt to different frequency requirements, allowing manufacturers to deliver a single standardized product that can be configured for various sub-bands rather than maintaining separate stock for each frequency.
3Adaptability or versatility
If the duplexer uses an adjustable frequency design, then the flexibility and application range improve, but the device complexity increases
Solution Approach 1:
The patent introduces a motor unit with control module that enables dynamic adjustment of the dielectric tuning component's position. This mechanical adjustment mechanism provides frequency flexibility while keeping the control system relatively simple, using basic motor control to achieve the desired frequency tuning.
