SMP Jack, 50 Ohm, 18 GHz — Gold Body, Through Hole
The SMP-MSCM-PCS-10: The gold-plated brass body and gold-plated center contact keep signal loss low across the band — the plating resists corrosion and maintains consistent contact resistance over repeated matings. The through-hole solder termination and shield termination are both solder-style, making it a straightforward board-mount part for RF modules, test equipment, or microwave assemblies.
What the 18 GHz and 500 Mating Cycles Mean for Your Design
The 18 GHz frequency max means this jack supports signals well into the K-band — useful for radar, satellite communications, and high-speed digital backplanes where the clock edge carries significant energy at those harmonics. The 500 mating cycles rating is high for an SMP connector; most SMPs are rated around 100 to 200 cycles. That cycle life comes from the gold-on-gold contact interface and the Catcher's Mitt feature, which keeps the center contact from taking the brunt of the misalignment force. For a test-port or a field-replaceable module that gets swapped regularly, this connector holds up longer before the contact resistance drifts.
