Multi-coax connectors and cable assemblies are specifically developed for intensive board end launch test. With the development of 5G and other optoelectronic communication technologies, the resources at the PCB board become more and more strained. The volume of traditional SMA or 2.92mm connector cannot be arranged on a PCB board, or even if they are arranged, the increased area leads to excessive insertion loss, which makes it impossible to verify the parameters of the chip or scheme. Several multi-coax connectors developed by Gwave are compatible with international brand products and offer great convenience to users.
