The new ultra-small IDT coaxial connector system offers excellent signal integrity, outstanding space savings and unparalleled reliability for mobile and many other applications. The system was originally designed to ensure that the signal passes smoothly through the hinges of the new Cyclotor with a rotating LCD screen. Therefore, the system uses ultra-fine coaxial cable can provide better than the FPC signal routing and space savings. Our dual-card cable grounding provides both superior electrical and mechanical grounding performance and is the key to making the system better than the other models. This method not only provides more reliable termination than manual soldering, but also reduces signal transmission losses up to 60% at 1-3MHz.
