Advanced wireless systems such as DAS (Distributed Antenna Systems) require RF components that, in addition to being highly efficient in signal transfer, must have low PIM (Passive Intermodulation) properties. The N type interface design is over 70 years old and has been replaced in many wireless site applications with the larger 7-16 DIN interface for better electrical and PIM performance. The 4.1-9.5 (Mini) DIN is essentially a compact version of the 7-16 DIN with similar electrical performance.
RF Industries provides between series adapters for the 4.1-9.5 (Mini) DIN, 7-16 DIN and N type interfaces. All adapters are manufactured with brass bodies in durable non-tarnish tri-metal (white bronze) plating with a PIM rating of less than or equal to -155dBc.
