Pulse, a Technitrol company, a leader in electronic component and subassembly design and manufacturing, announces a new family of cable television (CATV) RF transformers and RF diplex filters that meet Data Over Cable Service Interface Specification (DOCSIS) 3.0 design requirements for applications such as set-top boxes, cable modems and gateways. These components support frequency bands 5 to 65/85 to 1002 MHz, 5 to 42/54 to 1002 MHz and 5 to 85/108 to 1002 MHz, and are tuned and tested by Pulse to exacting specifications.
Pulse's initial offerings for this new family are two RF balun transformers, a transmission line transformer, part CX2240NL, and a flux coupled transformer, part CX2244NL. Also included is a new, small-package, surface-mount RF diplex filter, part C6164NL. All parts have been designed for new CATV technology products to exacting electrical specifications and come in industry-standard mechanical packages. The diplex filters provide electrical RF signal management with very low RF emissions and are fully enclosed in a metal shield or enclosure.
DOCSIS 3.0 is a CATV industry standard, developed to enable service providers to deliver more services by adding bandwidth to CATV’s existing hybrid fiber-coaxial infrastructure.
"Pulse RF DOCSIS 3.0 products are tuned and tested to exacting specifications in the factory. Pulse provides competitive market pricing and high-volume production capability. These products are immediately available, or Pulse can provide custom designs on request,” said Fred Roden, Senior Product Manager, Pulse Network Division.
Both the transformers and diplexers are RoHS compliant and meet open cable, cable labs, and data-over-cable service interface specifications. Pricing for the family of RF transformers ranges from $0.10 to $0.30 and parts are available in tubes or tape-and-reel. The RF diplex filter costs $1.50 and is available in trays.
