Carrier Aggregation (CA) is a process that bonds two or more blocks of spectrum into a wider channel, enabling faster data services in mobile networks, and allowing for mobile devices to communicate instantaneously on multiple LTE bands. But how do operators overcome the CA challenge of avoiding interference between the bands while minimizing insertion loss? The answer is multiplexers. Multiplexers are designed to integrate the required filters for multiple aggregate bands, provide isolation within and between the bands, and allow them to simultaneously connect to the antenna. This white paper discusses multiplexer solutions in detail and the many benefits they provide, including space savings, simplified designs, and cost reductions.
Researchers at Massachusetts-based Tufts University School of Engineering have built a chip-sized, low-power, high-speed modulator operating at above 14 gigahertz, with the potential to work at above 1 terahertz (THz) on the electromagnetic spectrum.
Electrical engineers at University of California, Los Angeles (UCLA) have developed a new type of circulator that uses a concept called Sequentially-Switched Delay Line (SSDL), which enables the simultaneous use of the same frequency for incoming and outgoing information in a single communications device.
Automobiles rely more and more on a growing number of wireless technologies to communicate with the outside world. Long-term technology goals include vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2X) communications for millions of automobiles as collision-avoidance and other intelligent transportation applications, which can be met using the IEEE 802.11p standard over the 5.9 GHz Dedicated Short Range Communications (DSRC) band. Avoiding interference in these applications requires high-performance RF bandpass filters capable of operating at high frequencies.
Scientists from the University of Nebraska-Lincoln (UNL) have invented a type of concrete mixture that can shield electronic systems from electromagnetic pulse (EMP) attacks and coronal mass ejections (CMEs). It's a cost-effective alternative to current EMP shielding solutions like metal enclosures.
