SMA Receptacle for 18 GHz Signal Paths
The 1-1478979-0: This is the through-hole solder version, with a gold-plated stainless steel body and a PTFE dielectric that holds impedance stable across the band. It's built for test equipment, RF modules, and instrumentation where a panel-mount or board-edge SMA launch needs repeatable performance.
What 18 GHz and 500 Cycles Mean on the Bench
The 18 GHz max frequency means this connector passes signals cleanly through the full microwave S, C, X, and Ku bands — useful for radar, satellite links, and high-speed digital clocks. The 500 mating cycles rating tells you the gold-on-beryllium copper contact will hold its contact resistance through repeated connect/disconnect cycles in a test rack or field-deployed system.
Mating and Termination — What Connects Here
This is an SMA receptacle — it mates with any standard SMA male plug (pin contact) with the same 1/4-36 UNEF threaded coupling. Through-hole mounting means the body legs go into the PCB and get soldered, giving a solid ground plane connection.
