Rated to 65 GHz, it sits at the top of the 925-16x family’s frequency range; the 925-165A-51S sibling tops out at 40 GHz, so this part is the choice when the signal path needs the full 65 GHz bandwidth. The gold-plated beryllium copper body and centre contacts handle repeated matings without degrading the RF launch, and the PTFE dielectric holds the impedance stable across the operating band. ## Active Sourcing — No EOL Pressure Listed as Active on the manufacturer’s lifecycle record. No last-time-buy or discontinuation notice applies. Rated for 100 mating cycles minimum, with typical life reaching 1000 cycles. The gold-over-beryllium-copper centre contacts resist fretting and maintain low contact resistance through repeated connects — suited for test-equipment rack interconnects or production harnesses that see frequent break-and-make. The snap-on fastening at both ends provides a positive tactile lock without requiring a wrench.","metaTitle":"Amphenol 925-166A-51S SMPM Jack-to-Jack Adapter, 65 GHz","metaDescription":"Amphenol 925-166A-51S SMPM jack-to-jack adapter, 50 Ohm, 65 GHz max, straight, gold-plated BeCu.
