Products Description
An N-type to SMA adapter is a radio-frequency coaxial accessory specifically designed to connect N-type and SMA interfaces, enabling circuit continuity and signal transmission. These two types of connectors differ in physical dimensions, thread specifications, and center pin thickness, making direct connection impossible. This adapter easily solves the problem of interface incompatibility.
Working Principle
The N-to-SMA adapter utilizes a straight-through signal path: the RF signal enters via the inner conductor at one end and is transmitted continuously through the adapter to the inner conductor at the other end, while the ground and shielding signals are simultaneously conducted through the outer conductor. The product serves solely to extend the signal path and convert the interface, without altering the original signal in any way.
