Ultra-durable 75 Ohm low loss cable assemblies

Paul Boughton

Pasternack has launched a new line of rugged 75 Ohm test cables with operation up to 3GHz that are specially designed to withstand the rigours of test lab use and communications systems.

Technicians commonly rely on these high frequency test cables in technologies such as cable TV, MoCA 2.0 and MoCA 1.1 (Media over Coax Alliance) and DOCSIS (Data over Cable Service Interface Specifications).

Pasternack’s new series of high performance 75 Ohm test cables are available in two configurations including a type-N male to type-N male or a type-N male to type-F male. Unlike most F connectors readily available on the market, these F connectors are designed to perform up to 3GHz which greatly broadens the usability and value of these test cables.

The connectors are also threaded to ensure an accurate and secure connection to both the device under test as well as the analyser. The test cables are suitable for engineering labs, production environments and quality testing facilities and are a good choice for use with 75 Ohm S-parameter test systems.

The assemblies have an insertion loss of < 0.5 dB@3GHz and typical return loss of 28 dB and are designed with an armoured jacket that meets ANSI/SCTE 99 2009 pull force and ANSI/SCTE 98 2009 tightening torque standards and are also capable of 100,000 bends minimum.

“Our new 75 Ohm test cables provide customers dealing with cable TV media hardware, set top box manufacturers  and broadcast engineers a new cost-effective source for high frequency 75 Ohm testing components,” says Steve Ellis, Interconnect Product Manager at Pasternack.
