Gold-plated beryllium copper centre contact. Panel mount with a flange, secured by the threaded coupling nut on the mating plug. The centre contact terminates via solder cup — you tin the centre conductor of the coax, insert it into the cup, and flow solder. No crimp tooling needed, but the solder joint quality directly sets the VSWR at higher frequencies — a cold joint or excessive solder wicking up the braid will shift the impedance match.","metaTitle":"TE Connectivity 1052543-1 SMA Receptacle, 50 Ohm, 18 GHz","metaDescription":"TE Connectivity 1052543-1 SMA receptacle, female socket, 50 Ohm impedance, 18 GHz max frequency, 500 mating cycles.
