CDM Electronics now offers flexible, phase stable cable assemblies for applications requiring low phase change with temperature

CDM Electronics, a leading distributor of commercial and military (MIL-SPEC) interconnect products, and premier provider of value-added contract manufacturing services, is now offering phase stable cable assemblies utilizing Times Microwaves Systems’ PhaseTrack™ -210 cables with TF4™ dielectric technology. This proprietary dielectric is a flouropolymer material process developed specifically for employment in RF and microwave applications requiring an extremely linear phase-temperature characteristic while addressing system designers’ demands for flexible cable. Notably, the cables boast phase change with temperature of < 1.5 ppm/degrees C (-55 degrees C to +85 degrees C), and will not develop a Teflon™ “knee” as they do not undergo the change in dielectric constant and abrupt change in electrical length that LD-PTFE (low-density Polytetroflourethelene) cables experience at normal room ambient (approximately +18 degrees C/+65 degrees F) conditions. As they additionally withstand repeated flexure while remaining within very tight electrical specifications, the assemblies are a superior alternative to LD-PTFE, SiO2 (Silicon Dioxide), or other conventional cables. Ideal for use by engineers designing high-performance systems, CDM’s phase stable cable assemblies may be confidently specified for deployment in a broad range of system platforms including ground, sea, and aerospace. They are singularly well suited for use in any mission critical application where temperature is fluctuating. Among the most common applications are satellite and military aircraft, phased array antenna systems, system interconnects and test and measurement environments. Featuring triple shield construction to provide shielding effectiveness of better than -100 dB, the cables’ outside diameter measures 0.210” (5.3 mm). Further, the 50-ohm impedance cables have a minimum bend radius of 1.00” (25.4 mm). They typically measure 0.14 dB per foot @ 2 GHz, 0.39 dB per foot @ 10 GHz, 0.59 dB per foot @ 18 GHz, and yield a low 1.35:1 VSWR. Phase stability with bending is 1 degree at 18 GHz. Their operating voltage is 2500 V (1000 V with SMA connectors), whereas cables’ operating temperature range is -55 degrees C to +125 degrees C. CDM provides both standard and custom phase stable cable assemblies with a broad range of cable lengths and connector interfaces including , N, MUHF, F, BNC, 716DIN, TNC, SMA, UHF QDS (quick disconnect), reverse polarity, and QMA.
