Module Connector Layout for Isolating IF and RF Test Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device modules, particularly those using flexible printed circuit boards (FPCBs), face difficulties in isolating and testing intermediate frequency (IF) and radio frequency (RF) signals for performance optimization due to the presence of power and control lines, making it challenging to connect external devices without altering the module structures.
Innovation Solution
An apparatus with dedicated lines for power, control, IF, and RF signals, including connectors and ports, allows for the connection of external devices to specific modules without changing the module structures, enabling testing and optimization of electronic device modules.

Engineering Contradiction Analysis
1Ease of operation
If a coaxial cable is used to connect external devices, then the device for testing and optimizing performance can be connected to a port, but in the case of FPCB with multiple lines (power, control, IF/RF), it becomes difficult to isolate and test only the IF/RF signal lines
Solution Approach 1:
The FPCB is divided into separate functional line groups: power lines, control lines, and IF/RF signal lines. This segmentation allows the IF/RF signal lines to be isolated and tested independently from other lines, resolving the difficulty of testing specific signal lines in a multi-line FPCB configuration
Solution Approach 2:
A connection part with external ports is introduced as an intermediary between the FPCB and external testing devices. This intermediary provides dedicated access points to the IF/RF signal lines, enabling external devices to connect and test these specific lines without interfering with power or control lines
2Adaptability or versatility
If the module structure is changed to enable testing, then external devices can be connected, but the original module structures must be altered
Solution Approach 1:
The testing capability is added in a new dimension by introducing external ports and a connection part that interfaces with the FPCB. This allows testing functionality to be added without changing the original module structures, as the testing access is provided through an additional dimensional layer (the connection interface) rather than modifying existing components
