Keysight Technologies Inc. announced that Smarter Micro has selected their PXIe modular vector signal test solution to accelerate the development of its latest reconfigurable multimode, multiband power amplifier. Smarter Micro is a fabless semiconductor company that designs and develops radio frequency (RF) integrated circuits for the communications industry. Smarter Micro is using Agilent’s test solutions in the design of its new S308 power amplifier, which significantly reduces the complexity of the fourth-generation mobile design.
To achieve multimode hybrid networking and seamless mobile roaming, mobile device manufacturers must meet the telecom operator’s multimode and multi-frequency specifications. Smarter Micro is addressing this need by using Agilent’s modular vector signal test solutions in the development of its multimode multiband RF frontend OMNI-Smart platform and the S308 reconfigurable multimode multiband power amplifier (MMPA). The S308 covers the full frequency bands from 698 MHz to 2690 MHz and is able to support UMTS, TD-SCDMA, FDD LTE and TD-LTE standards.
The full-frequency MMPA is designed to significantly reduce the mobile radio-frequency design complexity and development cycle, thereby reducing the total solution cost. However, multimode and multiband brings additional test challenges, such as longer test times during the product development, verification and manufacturing stages.
Smarter Micro used Agilent’s PXIe modular vector signal evaluation system solution during design verification of the S308 power amplifier. The system included the Agilent M9381A PXIe vector signal generator, M9391A PXIe vector signal analyzer, and automatic fast measurement software with frequency support up to 6 GHz and 160 MHz analysis bandwidth.
The Keysight test solution reduced the verification test times by enabling power servos to converge faster with outstanding linearity, repeatability and absolute amplitude accuracy. The test speed exceeded previous test instruments used and accelerated multiband, multimode and many other test evaluation requirements. In addition to design verification, the fast and accurate PXIe modular power amplifier test solution was suitable for high-volume production.
