Flexible 0.047 Low Loss Cable Assembly Performs to 67 GHz

August 13, 2020

For applications with limited space that need a flexible cable, Samtec has developed a low loss cable assembly with performance to 67 GHz. The RF047-A uses 1.85 mm male and female connectors and has a maximum VSWR of 1.4:1 to 67 GHz. Other connector options are male and female 2.92 mm and SMPM series. The connectors are solder clamp designs with fully captivated center contacts, and the body components are passivated stainless steel with gold plated brass solder ferrules and beryllium copper contacts.

Samtec has expanded its portfolio of precision microwave and mmWave cable assemblies to support the latest in 5G and other high frequency, low latency communications systems, offering a full line of off-the-shelf products with upper frequency performance from 18 to 110 GHz. Complete, end-to-end cable assemblies are available with a wide range of low loss and flexible cables, including 0.047, 0.085, 0.086 and versions optimized by Samtec. Cable connectors, board-level interconnects and cable assemblies are available with interface types of 1.00 mm, 1.85 mm, SMPM, SMP, 2.40 mm, 2.92 mm, 3.50 mm, SSMA, SMA, Type N and TNCA.

As one example, Samtec’s Bulls Eye®high performance cable assembly for test and measurement applications has upper frequency options of 20, 40, 50 or 70 GHz. The high density array enables smaller evaluation boards and shorter trace lengths, while the compression interface ensures easy installation and removal, while eliminating solder costs.

Samtec manufactures its microwave and mmWave products to precise mechanical tolerances to achieve superior performance and repeatability. It will customize products to meet a customer’s unique requirements, whether quick-turn modifications or new designs, and provide technical support to optimize launch designs, from simulation to testing.
