Smart Cars, Smart Antennas: Solving Tough Interference Challenges

Smart Car AntennasToday's on-the-go consumers expect to extend their digital lifestyles into their vehicles with wireless services, such as GPS satellite navigation, digital satellite radio, Wi-Fi connectivity and Bluetooth integration with their 4G smartphones. To establish an interference-free coexistence in the overcrowded wireless spectrum, the automotive technology industry developed the "smart antenna" concept — a multiband antenna system that can handle all those wireless standards in parallel. However, as more RF components for in-vehicle communications are squeezed into "sharkfin" roof antennas, high-performance filters are needed to keep those signals from interfering with one another. Enter TriQuint. TriQuint is dedicated to providing quality products to support the growing automotive market, as evidenced in the recent release of our very first NoDrift™ BAW filter. Our 885014 NoDrift BAW filter uses an advanced version of BAW to provide superior temperature stability to meet an especially challenging interference issue, allowing desired signals to transmit while rejecting undesired signals. Because our BAW technology solves some of the toughest filtering coexistence issues that RF designers face, a leading premium electric car manufacturer has chosen to incorporate our high-performance BAW filters into its rooftop antennas.

TriQuint Technology Connects the Human Heart

PacemakerTriQuint filters can be found in many places, doing amazing work. One of the latest examples comes from the innovative medical device field, where a TriQuint filter plays an integral role in device monitoring and transferring data to doctors from pacemakers implanted in patients' bodies.

Manufactured by one of the world's leaders in the implantable medical device industry, the pacemaker has a tiny radio component, which transmits periodically to a receiver near the patient that captures the data and can forward it to a doctor's office. Modern pacemaker batteries are designed to last many years, so radio components contained in them need to enable the radio to be incredibly efficient. TriQuint's filter technology helps to increase the range and efficiency of the radio by providing improved amplitude variation over the pass band frequency, which helps improve performance and extend the unit's battery life. TriQuint is proud of the many ways its products perform, and the filters inside life-saving pacemakers are a perfect example.

TriQuint BAW Filters Help Advance Antenna Arrays

HUMVEE radioModern phased array antennas (far more sophisticated than passive antennas) are dependent on multiple components working together in complete harmony. Sometimes called "active antennas," their uses are far-ranging, from defense communications to commercial to satellite applications. Lockheed Martin Corporation makes some of the most technically-advanced RF broadband transceivers for phased array antennas used in defense systems today. Working with Lockheed Martin, TriQuint produced miniature BAW filters that play a major role in facilitating the devices' operation at different broadband frequencies. TriQuint's BAW filters enable desired signals to travel through the receiver while spurious signals are rejected, and at a very low noise figure which is essential for optimal system performance. Lockheed Martin was pleased with the results, developing a research paper* that cited TriQuint's contributions. The paper was presented at the U.S. government's premiere microcircuit and critical technologies conference (GOMACTech) in 2013. TriQuint's BAW filters are ideal for next-generation antenna arrays and many other challenging applications that RF designers face every day.

TriQuint's space products including GaAs amplifiers, switches and filter technology have been aboard orbital payloads for more than two decades, including Boeing communications and navigation satellites. In all, Boeing projects that more than 250,000 TriQuint GaAs devices have gone into its Spaceway and other satellite programs to support broadband data, telecommunications and global positioning services.

TriQuint Enabling High-Power GaN Innovation for More Markets

cockpit-rfIn the world of high-power, high-frequency devices, gallium arsenide (GaAs), pioneered by TriQuint, was the history-making technology in the early 1980s. Among other advantages, GaAs delivered substantially less noise at higher frequencies than anything that had come before it. Not surprisingly, GaAs became the norm in mobile phones, satellite communications and high-frequency radar systems.

TriQuint continues to chart new territory, and has been one of the first to achieve breakthroughs in gallium nitride (GaN) technology. With inherently better efficiency, power handling and durability, GaN is seen as the emerging go-to technology for advanced RF systems. GaN-based amplifiers are providing RF system engineers with the flexibility to achieve significantly higher power and efficiency than GaAs while using fewer parts.

Its superior current efficiency and space-saving value are working to support customers that include some of the world’s largest companies that are developing commercial 4G systems, a defense flight system, and other defense / aerospace projects.

TriQuint Around the Solar System

Cassini-Huygens Spacecraft When a vehicle travels millions of miles through space and performs some of the most advanced exploration in history, we want to know what it has discovered. Sending communications from this distance requires the utmost in highest-performing components. A cooperative mission of NASA, the European Space Agency and the Italian Space Agency, the Cassini-Huygens spacecraft was launched toward Saturn in 1997. Its Huygens Probe included crucial equipment designed to communicate with the spacecraft throughout its mission to the surface of Saturn's moon, Titan. TriQuint's gallium arsenide (GaAs) device technology was at the heart of that connection that sent the findings back to Earth.

A few years later, Mars was the destination of two NASA rovers, the Spirit and Opportunity, also equipped with TriQuint GaAs amplifiers. The rovers arrived in 2004, and through a combination of superior design, interplanetary ingenuity and good fortune, Spirit continued to operate and communicate with Earth until 2010. Its sister probe, Opportunity, is still operational today.

TriQuint is proud that its space-qualified GaAs amplifiers are integral parts of these exploratory missions, sending data to the global scientific community. TriQuint components offer the type of rugged dependability necessary for the inherently challenging conditions of space exploration and, most importantly, communications back to Earth.

TriQuint Amplifier Powers New Options in Remote Cardiac Monitoring

Cardiac MonitoringA couple decades ago, cardiac monitors were purely local — meaning that their beeps, alarms and data were available only to medical personnel in physical proximity to the monitors. The introduction of telemetry meant that those alarms and patient data (e.g., pulse rates, blood pressure and other vital data) could be transmitted from patient hospital rooms to a nursing station or other centralized monitoring location. For years all that data had to travel over wires, limiting access to specific care settings within a medical facility.

Today, thanks to advances in wireless infrastructure technology, those same alarms and cardiac stats can be transmitted to doctors from ambulatory patients. Wireless telemetry systems can now wirelessly connect a central station and hundreds of transceivers or wireless bedside monitors, communicating vital signs as well as integrating real-time monitoring with lab results and radiology images, to make sure doctors have all the vital information at all times.

A Denmark-based industrial R&D firm, RTX A/S, worked with TriQuint supplier Richardson RFPD to qualify one of TriQuint's power amplifiers into a multibillion-dollar health care company's wireless telemetry system. TriQuint's power amplifier supports the high data rates needed for this long-range application, offering outstanding power-added efficiency for longer battery life and ensuring uninterrupted cardiac monitoring. The device was designed on TriQuint's advanced InGaP HBT GaAs technology to deliver superior reliability, temperature stability and ruggedness.

TriQuint: At the Front-End of Automobile Safety

automotive radarOver the last decade, automotive systems have advanced at a rapid rate. Applications that seemed like science fiction only a few years ago have now become standard. TriQuint's RF technology plays a critical role in one of the most impressive new applications, radar for adaptive cruise control.

This feature enables cars to sense objects in their path or coming toward them from another angle. Once a potential hazard is recognized, these sensors actively help drivers avoid collisions by working with the car's brakes — precharging them for faster response. TriQuint's 77 GHz portfolio for motion-sensing automotive and nonvehicular applications helped Delphi "...provide our customers game changing driver assist technology." One car manufacturer highlights that this radar technology is shared, in part, with the U.S. Air Force's F-22 Raptor aircraft. Flashy airborne cousins aside, these tiny but powerful modules are making car travel safer than ever, giving drivers and passengers greater peace of mind.
