1.0/2.3 Interface, 75 Ohm, 4 GHz — What This Connector Carries
The Amphenol RF 282124-75 is a 1.0/2.3 series jack, female socket, terminated by solder to the center contact and shield. The 75 Ohm impedance targets video distribution, broadcast, and CATV infrastructure — the 1.0/2.3 interface is the standard small-form-factor coaxial connector for those systems. Rated to 4 GHz, it covers the full L-band and most C-band downconverter feeds.
Mounting and Termination — Bulkhead Fit, Solder Joints
Panel mount with a through-hole solder termination for both the center pin and the shield. The bulkhead is secured from the front side with the included nut — the package ships as 2 pieces: one connector body and one nut. No crimp tool needed; the installer solders the center conductor and the braid directly.
Rated for 500 mating cycles. That is a service-life figure for a connector that will see regular reconnections — test equipment front panels, broadcast truck patch bays, or bench-top RF instruments. The gold-on-gold contact interface (gold body finish, gold-plated center contact) keeps contact resistance stable across those cycles without the fretting corrosion you get from tin-on-tin in a coaxial signal path.
