The rugged, lightweight construction of these assemblies delivers reliable performance with longer service life and reduced equipment downtime, which results in lower costs for testing in laboratory, production, and field test environments. Typical Applications Anechoic chambers Bench-top testing Nearfield scanners High throughput RF production testing Wireless telecommunication module testing Portable analyzers Electromagnetic compliance Test rack systems testing Vector network analyzers (VNAs) Automated test equipment Scalar network analyzers Antenna ranges Benefits of GORE PHASEFLEX Microwave/RF Test Assemblies Consistent, repeatable measurements with stable electrical performance up to 110 GHz Longer service life with durable construction that resists crushing, twisting, and kinking Enhanced phase and amplitude stability with flexure and temperature Increased throughput and reduced downtime with durable and reliable performance Courtesy, Agilent Technologies, Inc. Rugged Construction Delivers Longer Service Life Unlike conventionally designed RF test assemblies, GORE PHASEFLEX Microwave/RF Test Assemblies maintain excellent With an internally ruggedized construction, GORE PHASEFLEX Microwave/RF Test Assemblies maintain measurement repeatability phase and amplitude stability with flexure. The unique cable construction allows a small bend radius without affecting while withstanding demanding conditions such as continuous flexing, temperature cycling, broad temperature ranges, and performance (see Figure 1). Some cables have a minimum bend radius as small as 0.5 inches. frequent connect and disconnect. The consistent performance and reliability of these test assemblies increases the interval between time-consuming calibrations of the test system, which in turn increases throughput, and reduces the total cost of test. blies se icrowaveGORE PHASEFLEX M/Fr Tes T Msa GORE PHASEFLEX Microwave/RF Test Assemblies offer excellent Table 1: Test Assemblies with Guaranteed Phase 1 electrical and mechanical performance (see Tables 2 and 3 for and Amplitude Stability with Flexure product specifications).

The assembly was terminated with a short circuit and tested performance over a wide temperature range on a calibrated system. The VNA was normalized. A mandrel of 57 mm (2.25 in) radius was placed adjacent to the left or right side of the assembly, approximately at its midpoint. The chemical resistance assembly was coiled 360 around the mandrel and held in this position for one full sweep. high connector pull strength Maximum deviation over the frequency range of analysis was recorded. The assembly was then returned to its initial straight position, and the VNA was normalized again. The mandrel was placed on the opposite side of the assembly and the test was repeated. All of the assemblies above are tested using this test method. Precise and Repeatable Measurements The exceptional phase and amplitude stability of GORE PHASEFLEX Phase Matching Microwave/RF Test Assemblies ensures accurate and repeatable Upon request, phase or time delay matching can be specified for measurements. Although all of these assemblies exceed GORE PHASEFLEX Microwave/RF Test Assemblies with frequencies specifications for phase and amplitude stability, additional through 67 GHz.

This incorporated by design. type of specification allows replacement or addition of individual cables in a matched set. Relative match: Two or more assemblies whose time delay or phase length fall within a specified match window. Relative matching ensures consistent matching within a set of cables, but an assembly from one set may not necessarily be matched with cable assemblies in another set.
