RF Innovation Arises to Enable 5G

Fifth-generation (5G) networks represent the future of wireless technology. 5G environments are expected to be more complex and require more components, such as filters. Other aspects of 5G likely include more complex multiple-input, multiple-output (MIMO) antennas, new and adaptable waveforms, and improved interference mitigation. In a new white paper from Resonant, RF Innovation and the Transition to 5G Wireless Technology,” an overview of 5G is first provided. The white paper then delves into additional topics, with a focus on 5G RF filter requirements.

The white paper discusses how 5G is expected to dramatically improve performance in terms of network capacity, mobile connections, latency, cost, data rates, and coverage. It also describes the range of devices that will connect to the 5G network, such as mission-critical, Internet of Things (IoT), and next-generation mobile devices. In addition, several key factors that could help meet the targeted goals for 5G are explained: higher frequencies, massive MIMO, interference mitigation, and new and adaptable waveforms.

5G RF front ends are also examined, as the complexity associated with 5G could impact RF front-end development in a number of ways. These front ends will be driven by cost, power efficiency, and available space within a unit, according to the white paper. In essence, 5G RF front ends will need to be small, highly efficient, and manufactured in large quantities to meet global demands.

Filter requirements for future 5G networks are discussed, as a number of filtering challenges are mentioned. One of these challenges is complex multiplexing, which will be required as a result of carrier aggregation (CA). And because an increased number of filters will be required, their size and cost must continue to decrease. Additionally, higher frequencies will require filter technologies other than the current acoustic wave filters used in mobile devices. The white paper concludes with a description of Resonant’s Infinite Synthesized Networks (ISN) technology, which the company says is well suited to meet 5G requirements.
