1.0/2.3 (CC4) RF Coaxial Connectors are miniature, high-frequency RF interconnects designed for compact, high-density signal transmission applications. The designation "1.0/2.3" refers to the 1.0mm inner conductor and 2.3mm outer conductor dimensions that define this interface standard, while "CC4" identifies its common naming convention in telecommunication and broadcast equipment. Engineered to maintain stable 50Ω or 75Ω impedance depending on application, 1.0/2.3 (CC4) RF Coaxial Connectors support frequencies up to several GHz and feature a push-pull or snap-in coupling mechanism that enables rapid connection and disconnection without threading, distinguishing this series from screw-coupled connector types.
As a connector category, 1.0/2.3 (CC4) RF Coaxial Connectors are produced in multiple configurations to accommodate different cable types, mounting requirements, and coupling mechanisms, including cable mount, PCB mount, and bulkhead types. This series is widely used in telecommunication base stations, broadcast distribution equipment, and test instrumentation where compact size, secure locking, and high-density panel installation are required. Contact components are typically machined from brass or phosphor bronze and finished with gold or nickel plating to provide the conductivity and durability required for repeated mating cycles.

Application Scenarios and Selection Points
1.0/2.3 (CC4) RF Coaxial Connectors are applied in telecommunication base stations, broadcast distribution frames, test and measurement equipment, and other systems where compact, high-density RF connections with quick-locking coupling are required. When selecting a connector from this category, the following points are recommended for confirmation:
- Cable type and diameter — matched to the connector's clamp or crimp termination structure
- Mounting method — cable mount for jumper leads, bulkhead mount for panel fixation, or PCB mount for board-level integration
- Impedance matching — 50Ω or 75Ω configuration confirmed against the system transmission requirements
- Plating material — gold plating for improved conductivity and corrosion resistance, nickel plating for general durability
- Installation density — compact footprint suited for high-density panels and multi-channel racks
