These components support frequency bands 5-65/85-1002 MHz, 5-42/54-1002 MHz, and 5-85/108-1002 MHz. 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 small-package, surface mount RF diplex filter, part C6164NL. The diplex filters provide electrical RF signal management with very low RF emissions, according to the company, and they are fully enclosed in a metal shield or enclosure. 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
