Though the hype train of 5G may have some believing that true mm-Wave 5G will be showing up at your door any minute, the reality is that most 5G services will likely take years before they become viable. 3GPP Release 15 brought a new aspect to 5G beyond what many were expecting (other than the … Read Full Article
Though there are high hopes for Millimeter-wave 5G solutions to solve all of our bandwidth woes, there will likely still be a couple, to several, years before large scale deployments of mm-Wave 5G occur. For the time being, wireless service providers are focusing on developing hardware and prototyping the new Sub-6 GHz 5G NR bands. … Read Full Article
In last week’s post, we covered foundational details regarding PIM in modern wide-band and multi-carrier communication systems, with a note on upcoming 5G NR sub-6 GHz frequencies being added to the mix. This week’s blog expands upon that discussion and provides more details of PIM considerations specific to DAS. With DAS, another large PIM concern … Read Full Article
Passive intermodulation distortion is the result of discontinuities, metal-to-metal contact, and material properties that lead to nonlinear characteristics of typically linear passive transmission lines and components. PIM can be induced in a variety of RF components, such as connectors, adapters, cable, combiners, splitters, couplers, tappers, attenuators, terminators, antennas, and cable-to-board interconnect. PIM is generated when … Read Full Article
