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 entire frequency spectrum from 698 MHz to 2690 MHz and supports UMTS, TD-SCDMA, FDD LTE and TD-LTE standards.

The chipmaker appeared impressed by the test solution. “The speed, flexibility and accuracy of the PXIe modular power amplifier test solutions helped us accelerate our multiband multimode power amplifier S308 development,” said Guoyang Wang, Smarter Micro marketing vice president. “Agilent’s technical support was critical in the delivery of our OMNI-Smarter, the reconfigurable multimode multiband power amplifier, which we believe will be the revolutionary RF front-end solution in the 4G era.”

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 Agilent test solution reduced the verification test times by enabling power servos to converge faster with high 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.

Smarter Micro is a fabless semiconductor company that designs, develops and provides MMIC, RF and analog ICs used in wireless handsets, wireless communication infrastructure, remote radio units, RF test equipment, satellite communications, automotive remote control and wireless networks. The company’s product portfolio includes MMPA, WiFi PA, GPA, switch, mixer and other MMIC products.
