PS18
PS18 is a phase-stable RF cable for applications from DC to 18 GHz. Its low-density PTFE dielectric and shielded construction provide typical attenuation of 0.67 dB/m at 18 GHz.
PS18 supports phase-sensitive test and interconnect applications, including antenna measurements, radar development and beamforming systems. Phase change under flexure is specified at ±5° for the stated 360° bend test using an 80 mm radius.
