The 920-262J-51P: Rated from DC to 6 GHz, it covers common wireless bands including Wi-Fi, Bluetooth, and cellular sub-6 GHz without a VSWR penalty — the impedance match holds through the snap-on interface as long as the mating plug and cable maintain 50 Ohm characteristic impedance.
The 6 GHz upper limit means this jack handles the full sub-6 GHz spectrum with margin; above that, insertion loss climbs as the snap-on interface geometry approaches its electrical limit. The 100 mating cycles rating reflects the gold-over-beryllium copper contact finish — good for field-service or bench-test duty where the connector sees dozens to low hundreds of mates, but not a high-cycle production test socket application.
