SMP Jack for 20 GHz Signal Paths
The snap-on fastening with limited detent means the engagement force is lower than a full-detent SMP, which helps when the connector sits in a blind-mate or multi-port array where you don't want to fight a stiff push.
20 GHz vs 26.5 GHz — Bag vs Tape
The SMP-MSLD-PCS-20 shares the same SMP interface, limited detent, and 500-cycle life as the SMP-MSLD-PCS18T. The difference is the max frequency: 20 GHz here vs 26.5 GHz on the PCS18T. The PCS18T uses a PTFE dielectric and beryllium copper centre contact to hit the higher band; this part uses LCP dielectric and a brass centre contact, which keeps the cost lower for applications that stay under 20 GHz. Both ship in different packaging — this one in a bag, the PCS18T on tape and reel for automated pick-and-place.
