It is a right-angle through-hole mount part, with a gold-plated brass body and a PTFE dielectric. The centre contact is gold-plated phosphor bronze, rated for 500 mating cycles — enough for test jigs or field-replaceable modules where the connector sees regular mate/unmate duty. The operating temperature range of -65°C to 165°C is wider than many commercial SMA parts, making it a candidate for environmental chambers, outdoor radio heads, or aerospace instrumentation where the connector lives near the thermal extremes of the assembly. ## Key ratings and what they mean for your design The 50 Ohm impedance is fixed by the PTFE dielectric and the centre conductor geometry — this is a controlled-impedance interface, not a general-purpose signal connector. The 6 GHz maximum frequency means it covers L-band through C-band (GPS, Wi-Fi, 5G sub-6 GHz, radar IF) but it is not a DC-18 GHz part; if your signal path runs above 6 GHz, look at the 1057230-1 OSP jack which reaches 22 GHz. The 500 mating cycles come from the gold-on-phosphor-bronze centre contact — gold flash on the mating surface resists corrosion and keeps contact resistance stable over repeated connects. The threaded coupling gives a positive mechanical lock, so vibration won't unmate it, but the right-angle body means the cable exits parallel to the board — plan your enclosure clearance accordingly.","metaTitle":"TE Greenpar 3-1478978-1 SMA Receptacle, 50 Ohm, 6 GHz","metaDescription":"TE Connectivity Greenpar SMA receptacle, female socket, 50 Ohm impedance, 6 GHz max frequency, 500 mating cycles, -65°C to 165°C.
