The 135-3801-201 is a straight MMCX plug assembly connector designed for RF and microwave signal transmission. It features a 50-ohm impedance with a frequency range of 0–6 GHz and operates at a maximum working voltage of 170 VRMS at sea level, with a dielectric withstanding voltage of 500 VRMS minimum. The connector utilizes beryllium copper contacts with nickel and copper plating, a brass body with cold plating, and a Teflon insulator to ensure reliable performance. With an insulation resistance of 1000 megohm minimum and contact resistance specifications of 3.0 milliohm maximum for the center contact and 1 milliohm maximum for the outer conductor, this connector is suitable for precision RF interconnections in military and commercial applications requiring durability and environmental stability across operating temperatures from -55°C to +155°C.
