RF Cable Groups

This document has been composed to provide a industry reference for the major coaxial cable groups and their nominal specifications. Cable grouping is important to ensure compatibility across different manufacturers. Rather than introduce a brand new cable type with unique dimensions, RF cable manufacturers typically produce their cable to align with a well known cable group. This ensures connectors from one company can be used on another company's cable.

This can sound confusing, so to help illustrate the point consider the following example. Powertec produce coaxial cables such as our PTL-240, which sits alongside others including CommScope CNT-240, Telegärtner G30, Times Microwave LMR-240, and many others, who all manufacture an "L-240" group cable.

Group	Description	Max. Freq.	Att. @ 1 GHz Sort ascending
RG-400	RG-400 is a high temperature coaxial cable used in interconnections between telecommunications equipment and is widely used for commercial wireless applications such as avionics, radar, GPS, and medical systems. Featuring a PTFE dielectric and FEP jacket the cable is rated for operation up to 200°C ...	12.4 GHz	0.48 dB/m
RG-223	RG-223 is a type of RF coaxial cable that is similar in dimensions to the more common RG-58 cable. It differs due to its double shielding, which provides excellent protection against electromagnetic interference, enhancing the quality of signal transmission and supporting a higher maximum operating ...	12.4 GHz	0.44 dB/m
RG-142	RG-142 is a high temperature, double shielded coaxial cable used in interconnections between telecommunications equipment. This cable type is widely used for commercial wireless applications such as avionics, radar, GNSS, and medical systems. Featuring a PTFE dielectric and FEP jacket the cable is ...	12.4 GHz	0.42 dB/m
0.141 Semi-Flex	0.141" Semi-Flexible coaxial cable is hand-formable and microwave grade with mode free operation to 34 GHz. The cable's easy forming, excellent shielding, and very low PIM makes it a popular choice for use in component interconnection. The tin-soaked copper braid provides near 100% RF shielding and ...	34 GHz	0.39 dB/m
L-195	L-195 was designed as a high performance drop-in replacement for RG-58, RG-122, RG-303, and RG-142. The double shielded outer conductor provides excellent RF shielding exceeding 90 dB, and its PE jacket provides for a service life in excess of 20 years. L-195 cables are occasionally referred to as ...	41 GHz	0.39 dB/m
0.141 Semi-Rigid	0.141" Semi-Rigid coaxial cable provides mode free operation to 34 GHz. The sold tin-plated copper tube effectively provides 100% RF shielding with shielding effectiveness exceeding 110 dB, and enables the dielectric and center conductor to remain precisely spaced. This results in optimum impedance ...	34 GHz	0.38 dB/m
RG-402	RG-402 Semi-Rigid coaxial cable is a MIL-DTL-17 qualified series providing mode free operation to 34 GHz. The sold tin-plated copper tube effectively provides 100% RF shielding with shielding effectiveness exceeding 110 dB, and enables the dielectric and center conductor to remain precisely spaced ...	34 GHz	0.37 dB/m
L-200	L-200 was as a high performance drop-in replacement for L-195. The cable was designed with a marginally larger center conductor than RG-58 and LMR-195 to provide reduced attenuation, while still maintaining a 4.95 mm overall diameter. The double shielded outer conductor provides exceptional RF ...	36 GHz	0.34 dB/m
L-240	L-240, sometimes referred to as LMR-240, is a low loss coaxial cable with a medium sized 6.10 mm outer diameter. This series is without a doubt the most popular choice of RF cable, due to its efficient compromise between performance and cost. L-240 cable provides the flexibility and easy ...	31 GHz	0.26 dB/m
0.250 Semi-Flex	0.250" Semi-Flexible coaxial cable is a formable, microwave grade with mode free operation to 19 GHz. The tin-soaked copper braid provides near 100% RF shielding and the malleable nature of the outer jacket eliminates solder joint failures and allows bends immediately behind the fillet. Standard 0 ...	19 GHz	0.25 dB/m
RG-214	RG-214 is a heavy duty 50 Ω coaxial cable used in high frequency telecommunications applications and is widely used for commercial wireless applications such as broadcast, UHF, and military. The cable's large center conductor, good shielding, and large overall diameter ensures low attenuation with ...	11 GHz	0.24 dB/m
RG-393	RG-393 coax is commonly used in telecommunications and broadcast equipment. This type of coaxial cable is often used in military equipment, as well as in commercial applications requiring high temperature operation. RG-393 cable is generally approved for direct burial. Equivalent Mil-Spec standard is ...	11 GHz	0.24 dB/m
