The 1129-6279 is a straight, panel-mount SMA female to SMA female adapter. It is engineered for high-frequency performance, operating from DC to 18.0 GHz with a characteristic impedance of 50 Ohms. The adapter features a low insertion loss of 0.04dB times the square root of the frequency in GHz. Constructed with a passivated stainless steel body and gold-plated beryllium copper contacts, it ensures durability and reliable signal integrity. An included conductive EMI gasket makes it suitable for applications requiring protection against electromagnetic interference.
