Mobile

Mobile devices—smartphones, phablets, and tablets—are everywhere. From communicating with friends, family and coworkers, to filming videos, watching movies, playing games, and managing fitness goals, today’s mobile devices have become essential to everyday life. 

Smartphone demand is expected to exceed 1.3 billion units globally in 2020.  While overall smartphone sales have remained relatively steady, the demand for more features and reduced latency is significantly driving up the internal content and complexity. Mobile wireless networks have evolved from predominantly voice-centric networks to advanced high-speed networks that deliver voice, video and data, enabling consumers to access bandwidth-intensive, rich media content on mobile devices through applications such as videoconferencing, streaming media and interactive gaming. Due to ever-increasing data consumption demand, mobile devices must be able to support and manage higher bandwidths made possible by fifth generation wireless (5G) transmissions.

Mobile devices have evolved from supporting only a single cellular standard operating on two or three frequencies and using a single antenna, to supporting multiple wireless protocols and frequency bands, and integrating multiple antennas.  As a result of 5G, the growing number of bands and expansion of multiple-input and multiple-output (MIMO) combinations are exponentially increasing the complexity of the radio frequency front end (RFFE). More than 40 different frequency bands are currently used across the globe to support the long-term evolution (LTE) standard, with the FR1 and FR2 frequency band applications for new radio (NR) expected to add to that. This complexity is driving the need for improved performance in the RFFE components—specifically low loss, low noise figure, high linearity, high isolation and high out-of-band attenuation.

Based on our UltraCMOS® technology, our RF solutions are ready for 5G’s complex requirements and can be found in many top-tier smartphones. In addition to being a member of the 3rd Generation Partnership Project (3GPP), pSemi works closely with global operators and industry organizations to identify future challenges and develop cutting-edge RF solutions. Our products are optimized to meet the tight area requirements of smartphone form factors while still delivering best-in-class RF performance.

Communication Infrastructure

With increased data consumption and mobile device connectivity requirements, demand for base stations is also growing. A base station is a fixed-location wireless communication station, with one or more antennas, that receives and transmits signals in a cellular network to phones and other devices.

The combination of an increasing global subscriber base, expansion of advanced wireless networks and the proliferation of powerful devices offering high-speed wireless Internet access has dramatically increased mobile data traffic. This increase in data traffic is straining the existing wireless network infrastructure. As a result, operators are expanding their network capacity by acquiring additional wireless spectrum and by aggressively deploying long term evolution (LTE), time division-LTE (TD-LTE) and 5G New Radio (5G-NR) networks.

In addition to the traditional macro network, which is used for wide area coverage, the rollout of smaller base station formats also are being pursued. These formats include picocell, small cell and carrier-grade Wi-Fi solutions to support growing data requirements in urban areas. These products will increase data capacity and will be used in areas with poor coverage.

Wireless backhaul is one of many options to connect the base station to the core network, and, as data consumption grows, so does the need for high-speed backhaul. Line of sight (LOS) microwave solutions are used extensively and offer high data rate wireless backhaul solutions. With the rollout of small cells in urban environments where LOS is not always simple to achieve, non-line of sight (NLOS) solutions are being deployed, which offer lower data rates but can be used to increase the flexibility of the backhaul deployment.

pSemi offers a variety of RF components and solutions to address challenges that customers are experiencing with emerging new techniques such as state-of-the-art beamforming and multiple-input, multiple-output (MIMO). Key areas pSemi proposes value in are high linearity, high input power handling, low power consumption, high channel isolation and smaller form factor integration in both FR1 and FR2 bands.

Cable Broadband

With increasing demand on very fast download speeds for movies, videos, photos and other content over existing cable connections, cable providers have evolved the Data Over Cable Service Interface Specification (DOCSIS) standard over decades from version 1 to 4 in order to achieve high data rates of 10 Gbps downstream and 6 Gbps upstream, and to compete with fiber technology.

It is expected that the next major broadband update, DOCSIS 4, will be able to use at least 3 GHz of RF spectrum available on existing coaxial cable for high-speed Internet, a dramatically higher upload speed increase than the 1.8 GHz currently needed to support DOCSIS 3.1 FD. DOCSIS 4 will enable multi-gigabit symmetrical services while staying compatible with DOCSIS 3.1. DOCSIS 4 will also require higher-order quadrature amplification modulation (QAM) schemes up to 256-QAM for downstream and 16-QAM for upstream. For these reasons, linearity RF components that can meet higher downstream modulation error ratios (MER) are essential.

pSemi offers RF switches for cable modems, set-top boxes and residential gateway features with unmatched linearity performance, such as IIP3 and harmonics, enabled by UltraCMOS® technology along with excellent isolation, low insertion loss, low spurious emissions, and a CMOS/TTL-compatible control to address the needs of wired broadband applications.

Test & Measurement

The transition to 5G from previous generation standards 2G/3G/4G is driving the demand for data traffic and mobile device connectivity. Operators are trying to increase data throughput and enhance connectivity; therefore, wireless infrastructure manufacturers are deploying new-generation base stations in the field. To address dramatically increased mobile data traffic, new wireless spectrums are required, and test and measurement (T&M) equipment must extend their frequency coverage range as well. Therefore, extensive ongoing research and field trials on 5G technologies is boosting demand for RF T&M equipment and will continue to do so.

The continuous evolution of communication standards is a driving force for RF test equipment in commercial and military radios. New standards dramatically increase demands for test equipment from the R&D phase to the production phase. 802.11ax measurement is more difficult to perform than that of previous standards, so new RF test instruments are needed to handle new requirements.

In addition, the automotive industry has growing demands to address trends related to connected cars and autonomous driving applications. Market participants are receiving requests from non-traditional radar customers focused on automotive applications as they work on technologies related to driverless vehicles, collision avoidance and the new 802.11p Wi-Fi standard.
