Microwave connectors are employed for use in cabled interconnections, for direct interconnection of packages, and for interconnection of plug-in super component modules. Important electrical specifications for all microwave connector types are insertion loss, VSWR, and RF leakage. A RF connector is a part that is adopted to obtain a permanent or temporary connection for the transferring of RF energy from one circuit or cable to the next, preferably at constant impedance. Coaxial connectors are used to connect these cables to bulkheads and circuit cards.
