Lisle, Ill. − Molex Inc. has introduced a line of microwave cable assemblies that achieve 85 to 88 percent velocity of propagation (VOP) for increased signal speed, exceeding aerospace and defense specifications. The Temp-Flex air-dielectric ultra-low-loss flexible microwave coaxial cables feature a patented dual monofilament air-enhanced design and a helically wrapped shield.
The highly reliable return-loss performance of the Temp-Flex coaxial cables optimizes voltage standing wave ratio (VSWR) characteristics for the complete end-to-end interconnect, said Molex. The helically wrapped flat-wire shield with braid provides "excellent shielding effectiveness, enhanced flexibility and superior electrical performance compared with semi-rigid microwave coaxial solutions," added the connector maker.
The coax cable solutions are said to provide extremely stable electrical performance with minimal impedance and insertion loss variation in dynamic applications. In addition, highly consistent manufacturing processes ensure the industry's smallest mechanical tolerances: 0.047", 0.086", 0.141" shield OD constructions, said Molex. The flexible microwave coaxial cables offer 100 dB or greater shielding effectiveness and protect signals from internal and external interference.
"Meeting requirements for strong signal performances with limited signal loss is a growing challenge in high-frequency applications," said Jeet Sanyal, Molex's engineering manager, Temp-Flex, in a statement. "Industry leading Temp-Flex microwave coaxial cables deliver up to 88 percent VOP – exceeding stringent aerospace and defense specifications while achieving optimum phase stability and bandwidth."
Molex developed the Temp-Flex microwave coaxial cables for device manufacturers specifying microwave coaxial cables in high frequency aerospace, defense and commercial applications, including radar, military vehicles, satellites, space, missile, radio frequency (RF) ablation, test and measurement equipment.
Availability: Temp-Flex microwave coaxial cables are now available as assemblies from Molex in select cable sizes and connector types.
