18 GHz Bandwidth and 500-Cycle Durability
The 1050770-1: Rated to 18 GHz, this plug supports the full SMA frequency range without the roll-off seen on lower-cost 12 GHz designs. The 500 mating cycles mean the interface holds repeatable VSWR performance through multiple connect-disconnect cycles in test bench or calibration setups — the gold-on-gold contact pair resists wear that would shift the impedance at the interface.
For new designs, a parametric search on SMA plugs for RG-405 cable at 50 Ohm and 18 GHz will identify current-production alternatives.
It is built for RG-405 (.085" Semi Rigid) cable — the dielectric is PTFE, and the body finish is gold with passivated stainless steel. The package includes two pieces: the connector body and the centre contact, ready for field or bench assembly.
