With the continuous innovation and development of mobile communication devices and technologies, mobile phones, as the most common mobile communication tools, have attracted the attention of a large number of mobile phone manufacturers due to the increasing market demand and the increasingly mature competition environment. In the context of the 3G era of wireless communications, handset manufacturers are continually investing in the development of handsets capable of supporting more frequency bands and streamlining RF architectures, using multiple frequency bands such as GSM, EDGE, WCDMA and HSPA in 3G handsets. The interface modules are integrated in a highly integrated, optimized RF module. Continuous improvement and upgrade of RF chip technology has become the key to 3G mobile phone design RF solutions. However, as mobile phone sizes continue to decrease and users' expectations for mobile phone performance increase, traditional mobile phone integrated circuits and components are gradually becoming a limitation of wireless communication development. Under this technology bottleneck, Paratek, which specializes in the production of mobile phone film materials, has drawn the attention of the industry.
Founded in 1998, Paratek is a privately held company based in New Hampshire. Paratek's investors include venture capital firms such as Polaris Ventures and STMicroelectronics, Europe's largest chipmaker. Since its inception, Paretek has focused on proprietary tunable RF material technology (ParaScan), which has been developed to produce integrated circuits and other components that improve handset performance. Reducing the number and size of mobile phone components such as antennas, meeting the front-end requirements of each RF, and successfully solving many technical problems such as reducing power consumption, enhancing tuning range and high Q. As the basic technology of Paratek, ParaScan provides a new RF tuning technology solution for the wireless field.
Leading RF tuning technology
Paratek designs and manufactures adaptive front-end RF component solutions for wireless mobile devices. Paratek's products enable three applications for multi-mode and multi-band operation:
1. Adaptive Impedance Matching Module (AIMM)
2. Broadband filter and pre-selected RF front-end equipment
3. Radio Antenna Frequency Tuner (RAFT)
Leading material technology
All of Paratek's products are based on two proprietary materials that are known as ParaScan and ParaStak. ParaScan technology is designed to produce passive ParaTune tuner ICs by using a range of specialized composite ceramic materials. These RF tunable capacitor circuits are used in filters, power amplifier chips, adaptive antenna matching circuits, and phase shifters. Wait. As the basic technology of Paratek, ParaScan provides a new RF tuning technology for the wireless field.
The most striking feature of ParaStak's tunable material technology is its complex RF circuitry and extremely small size. ParaStak combines ASIC chips with passive components using industry-standard components and technology in a single package. The technology works in conjunction with RF and digital ASIC devices and features proprietary 3-D overlay and miniaturized RF components and their functional blocks. ParaStak's small package and fewer pins mean superior performance and reduced miniaturization costs.
Core material ParaScan and core product ParaTune
ParaScan and ParaStak form the foundation of RF products and solutions. At the same time, ParaStak's adaptive impedance matching technology improves the power amplifier's efficiency, linearity, link margin, antenna size and battery life while improving the energy transfer of the entire RF system under all modulation protocols.
Since a single antenna can only cover a fixed frequency range, electronic designers are often forced to use multiple antennas to cover a wider range of bandwidth. This situation directly hinders the styling needs of ultra-thin mobile phones. The RAFT (Radio Antenna Frequency Tuners) technology is highly valued for its ability to greatly reduce the size of the antenna. The RATF replaces the fixed components on the feed point of the traditional antenna, maximizing the energy transfer in each band, making the antenna smaller, improving performance and achieving multi-band pre-adaptation.
Better wireless communication
Paratek's products will allow customers to achieve the following goals in the wireless communications industry:
1) The customer can rely on only one tunable antenna to transmit and receive signals in multiple frequency bands. The highly miniaturized and highly efficient antenna will match any communication band. This tuning capability will significantly improve the performance of next-generation commercial mobile devices and government/military radios that rely on software;
2) Against the effects of impedance mismatch. Paratek's Adaptive Impedance Matching Module (AIMM) instantly adjusts the impedance to 50 ohms under automatic mismatch conditions. This closed-loop system has extensive tunable self-correction control to optimize the performance of the power amplifier for the antenna and any mobile device environment.
3) Extend battery life and reduce component count. Using the AIMM module, tunable power amplifiers can be tuned through integrated, optimized load matching for different frequency bands and modes of operation, significantly increasing the battery life of mobile handsets.
4) Take advantage of the new wideband filter. Paratek's wideband filters based on fixed filtering technology help customers reduce size, weight and power consumption. Paratek has delivered and deployed filters that operate between 30 to 450 MHz, 225-960 MHz and 1350-2500 MHz. At the same time, Paretek is continually optimizing its solution to expand its frequency coverage to 5 GHz and eventually to 20 GHz.
