Japanese scientists have built a terahertz (THz) transmitter capable of transferring data at speeds of 105 gigabits per second using the frequency range between 290 GHz and 315 GHz. That's ten times faster than fifth-generation mobile networks (5G) offer.
Today’s smartphone market has expanded into several categories with differing design goals and priorities, which require different approaches to RF front end (RFFE) integration. Modern packaging techniques make it possible to combine multiple RFFE components into integrated modules which help smartphone manufacturers accelerate the design and manufacture of new handsets. However, since there are two key smartphone categories – flagship phones and mid-tier and entry-level handsets – it raises the question of what would be the right level of RFFE integration and the best integration approach for each one?
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.
