- Buyers Guide
EAM's low loss cable assemblies provide the highest level of electrical performance for applications requiring extremely low attenuation over a broad frequency range. By combining silver-plated copper center conductor, expanded PTFE tape dielectric, aluminum polyester or polymide tape, silver-plated copper outer braid, and FEP jacket, these low loss cable assemblies achieve outstanding electrical characteristics to 18 GHz. Available in custom lengths with outer cable diameters of 0.195 and 0.335 in., EAM's low loss cables feature custom connectors with rugged stainless-steel solder-clamp construction for optimum reliability and performance.
For example, EAM's low loss cable assemblies with 0.195-in. outer diameter (LL142) minimize attenuation to typically 0.082 dB/ft. at 1 GHz, 0.250 dB/ft. at 10 GHz, and 0.360 dB/ft. at 18 GHz (see upper plot). With a minimum bend radius of 1 in., these low loss cable assemblies can handle 720 W CW input power at 1 GHz and 220 W CW input power at 10 GHz, with outstanding VSWR performance (see lower plot). For even less loss, cable assemblies with 0.335-in. outer diameter (LL335) achieve typical attenuation of 0.048 dB/ft. at 1 GHz, 0.17 dB/ft. at 10 GHz, and 0.22 dB/ft. at 18 GHz. These cable assemblies feature a minimum bend radius of 1.7 in. and can handle 1800 W CW input power at 1 GHz and 600 W CW input power at 10 GHz. Both sizes of cable assemblies offer shielding effectiveness of greater than 95 dB with low coefficient of expansion over a wide temperature range of -55 to +200°C to ensure that attenuation and phase performance remains stable over time and temperature.
EAM's low loss cable assemblies are available with a wide range of connector choices, including SMA, Type N, and TNC connectors.
