F-Type Connector Series

Type F connectors serve a low cost market with prices from $0.20 to $0.95. Amphenol Connex provides a high performance, cost-competitive alternative. All connectors comply with a 3/8-32 thread specification.

The Type F features a threaded coupling mechanism. Primary applications are for cable television (CATV), set top boxes, and cable modems.

With the deployment of 750 MHz Hybrid Fiber Coax (HFC) networks, it became increasingly obvious that existing low performance F receptacles could not be used in high speed cable modems and customer interface units (CIUs). The industry has challenged connector manufacturers to develop high performance connectors featuring -30 dB return loss at 1 Ghz. Additional, these high performance connectors must still accept .022-.042 in. diameter conductors.

Features & Benefits

  • Patent pending contact design provides a truly cylindrical coaxial contact and provides superior RF performance and excellent insertion/withdrawal characteristics.
  • 30dB return loss to 1 GHz ensures a high performance specification that outperforms competition.
  • Multiple PCB mount packages: surface mount, edge mount, right angle and straight, meets many customer application needs.
  • Accommodates .022-.042 inch center conductor sizes. One connector accommodates a wide range of cables sizes reducing part numbers.
