With a new and innovative design, the 4.3-10 interface offers very low PIM (Passive Intermodulation) performance and eliminates the risk of operator error during installation. The unique design of 4.3-10 interface makes the connector’s electrical performance independent of applied torque and good PIM (dynamic) performance is guaranteed even when connectors are mated without torque. Unlike 7/16, N and 4.1/9.5 which make axial contact, the key feature of the 4.3-10 interface is the separation of the electrical contact and mechanical stop by making a radial contact. The difference in design and construction of 4.3-10 implies that the standard calibration rules of axial contact interfaces do not apply and require some clarification. 2 NEED FOR CALIBRATION KIT? The interfaces which function with a front/axial contact, e.g., N, 7/16, PC 3.5, the reference plane is well defined and a precise calibration can be made on this defined distance. As there is not a front contact in 4.3-10 interface, it does not have a defined reference plane which is needed for precise measurements using calibration kits.
