China's RF connectors in various size categories target mostly communications, medical, automotive and military uses.
SMA, SSMA, SMB, SSMB, BNC, MCX, MMCX, N, F, 7/16 DIN, TNC and I-Pex-compatible types make up the RF connectors range in China. These come in male and female, and 50 and 75ohm-impedance types, mainly for communications, medical, automotive and military applications.
The connectors have copper or brass contacts with gold or nickel plating. The insulators are made of PE, PTFE, nylon 66 with glass fiber or thermoplastic.
The majority of manufacturers obtain metal and plastic from domestic providers, turning to foreign sources only when required.
Product prices have been fluctuating with the cost of materials, especially copper. This trend is expected to continue until 2018.
The products in this gallery have been handpicked by our China-based market analyst for representing current trends in RF connectors.
