What Is QN RF Connector In the world of radio frequency (RF) connectors, the QN connector series stands out as a high-performance solution engineered for quick and reliable RF connections. With a characteristic impedance of 50 Ω and an impressive maximum operating frequency of 11.00 GHz, QN connectors offer exceptional RF performance while introducing the convenience of a 360º rotating snap-on locking interface. This innovative coupling mechanism, known as Quick Lock Coupling, improves packing density and eliminates the need for torque wrench clearance, making it a valuable addition to the connector landscape.
