20 GHz SMP Jack, Smooth Bore, SMT
The SMP-MSSB-PCS17T: The Smooth Bore feature means there is no detent — the snap-on retention is constant, giving a consistent mating force across 1000 cycles. That makes it a solid pick for blind-mate board-to-board or cable-to-board links where you don't want a tactile click, and the 20 GHz ceiling covers most microwave and high-speed digital links up to Ka-band.
What the 20 GHz and 1000 Cycles Mean on the Bench
The 20 GHz max frequency is the usable bandwidth before the return loss climbs — for a 50 Ohm system, that covers everything from L-band through Ku-band and into the lower Ka-band. The 1000 mating cycles is double what many SMP connectors carry; the gold-on-brass centre contact and gold body finish keep the contact resistance stable over those cycles. The Smooth Bore interface mates with standard SMP female receptacles — no detent means the insertion force stays low, which matters when you're mating a board stack or a test cable repeatedly.
SMT Termination and Board Fit
Surface mount termination with a solder shield termination — the outer conductor solders to the board ground plane, which keeps the RF return path clean. The Liquid Crystal Polymer (LCP) dielectric holds up through reflow and gives stable impedance up to 20 GHz.
Smooth Bore vs Limited Detent — A Quick Cross-Shop
The difference is the dielectric: the PCS17T uses LCP, the PCS15T uses PTFE.
