  • Publication number: 20170131489
    Abstract: A connector assembly includes a printed circuit board (PCB) enclosed within a metallic cover. The PCB has an exposed mating port at a front region, and a transmission region around a rear region. A latch structure associated with a pulling tape is provided on the metallic cover. A CMOS (Complementary Metal-Oxide-Semiconductor) IC and a control IC are mounted upon the PCB and electrically connected to the mating port for transforming the electrical signal to the THz electromagnetic waves. An optional lens is optionally located at the rear region to refocus the THz electromagnetic waves to a low dielectric constant wave guide for further transmission. A system includes a pair of connector assemblies oppositely arranged and linked with each other via the low dielectric constant wave guide.
