SMA Panel-Mount Receptacle, 12.4 GHz — 132147-48
The extended PTFE insulation (listed as Extended Insulation) adds creepage distance past the connector face, useful where the panel cutout or adjacent hardware could otherwise compromise the signal path. Gold-plated brass body with a gold centre contact over beryllium copper, rated for 500 mating cycles. The threaded fastening and solder shield termination suit it for semi-permanent panel installations where the cable is soldered once and the connector stays put.
12.4 GHz vs 18 GHz — Where This SMA Sits
The 132147-48 is rated to 12.4 GHz, while the sibling 132134-11 (same flange-mount SMA receptacle, same gold body, same 500-cycle contact) is rated to 18 GHz. The difference is the upper frequency limit — the 132147-48 covers L through X band and most Ku-band satellite downlinks, but not the full SMA ceiling. If your signal path stays under 12.4 GHz, the 132147-48 is the correct call; if you need the extra headroom to 18 GHz, the 132134-11 is the drop-in swap at the same footprint.
