SMA Panel Receptacle for 18 GHz Signal Paths
The 1052543-1: Rated to 18 GHz, it handles the full L-band through Ku-band spectrum — common in microwave test equipment, antenna feeds, and instrumentation backplanes where the signal integrity up to the panel edge matters.
What the 18 GHz and 500-Cycle Ratings Mean
Rated to 18 GHz with 500 mating cycles. 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.
