Mobile devices—smartphones, phablets, and tablets—are everywhere. From communicating with friends, family and coworkers, to filming videos, to watching movies, to playing games, to 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.
Our Products for Smartphones
Personal computers are used throughout businesses, homes, educational facilities, and other institutions to perform individual or shared word processing, Internet research and communications, information and file sharing, and other applications. Tens of millions of PCs are shipped worldwide each quarter.
Power management is a critical aspect of personal computer use from both a physical size perspective and a longevity perspective. Power components occupy much space inside PCs, so manufacturers want a smaller power footprint. Backlit displays drain battery power; users want longer-lasting batteries.
pSemi’s power products, which are scalable by power and input voltage, enable huge increases in power conversion efficiency, with a substantially-reduced size and lower overall cost. pSemi produces LED backlight boost converters, which provide up to 10% improvement in LED backlight efficiency, and buck regulators for core voltage (VCORE), VCCIO, memory, field programmable gate arrays (FPGAs), and application-specific integrated circuits (ASICs), which provide an improvement in conversion efficiency.
Our power products reduce PC power management footprint by >50%, height of components by factor 3x, and losses in power management by up to one half, while increasing platform run-time by more than one hour.

With increased data consumption and mobile device connectivity demands, demand for base stations is also increasing. 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 LTE-A 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 the challenge 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.

Data centers, which house computer systems and associated components, are being affected by increasing demands for bandwidth, especially because of cloud adoption. The cloud is shifting which data centers host it, and where. Data centers must be able to accommodate the data demands driven by cloud-based applications with larger bandwidth and faster speed requirements.
Because of these increasing demands, data centers are employing fiber optic cabling and optical transceiver solutions. Fiber optic cables transmit data faster than many other mediums, have less attenuation, and are not affected by electromagnetic interference (EMI). Optical transceivers transmit and receive data, in the form of light pulses, using fiber optic technology.

The automotive market is driving large growth in the RF semiconductor arena, primarily with the growth of telematics and infotainment systems.
The telematics umbrella covers many of the high-growth segments of the automotive sector. These applications include GPS navigation, integrated hands-free cell phones, wireless safety communications and automatic driving assistance systems such as automatic cruise control and anti-collision radar.
The other large growth area is in the in-car entertainment sector where audio, visual and media entertainment systems are being integrated into vehicles. These devices are now commonly being connected via either a Wi-Fi or cellular internet connection to enable a connected car.
Another force driving growth in the automotive market is the advent of driverless cars. Driverless vehicles rely on connected sensors that can perceive the vehicle’s state and external surroundings and devices.

The Internet of Things (IoT) is the network of devices or objects that are connected to the Internet via cellular networks, Wi-Fi, and the like. IoT enables a broad array of devices to be connected including robots on manufacturing floors, healthcare devices, wearable and embedded products and home/factory energy management systems. The common theme for these IoT devices is their ability to sense and communicate with their environments, including other devices, and to collect data that is used to optimize and improve their performance.
Many of these devices are wireless and battery-powered and, in many cases, are required to have multiyear lifetimes. These key characteristics drive the need for high-performance, low-power devices that must be cost effective in order to be viable for the huge potential volumes being tied to IoT.
