The 50 Ohm impedance and 18 GHz max frequency tell you this connector holds a controlled 50 Ohm line through the transition; above 18 GHz the geometry starts to radiate and the VSWR climbs. The gold-plated stainless steel body and gold-over-brass centre contact give it 500 mating cycles before the plating wears through — enough for test equipment or field-service gear that gets reconnected weekly. ## What the Kit Includes This is a 6-piece kit: the SMA plug body, a braid clamp, a cable clamp, the centre contact, and two PTFE insulators. The centre contact is solder-terminated — you tin the centre conductor, slide the contact on, and solder through the inspection hole. The shield is captured by the clamp, not soldered, which makes field termination faster and avoids cold solder joints on the braid. ## Active Production — No LTB Clock No last-time-buy notice or phase-out date is on record. There is no direct replacement or cross-reference on file; if you need a substitute, the pin-compatible alternative would be another SMA plug with the same cable group and 50 Ohm impedance, but no official TE cross-reference exists for this order code.","metaTitle":"TE Greenpar 1-1478908-0 SMA Plug, 50 Ohm, 18 GHz","metaDescription":"TE Connectivity Greenpar SMA plug, male pin, 50 Ohm impedance, 18 GHz max frequency.
