RF Micro Devices Inc. (RFMD) has extended its line of PowerSmart power platforms that now includes multiple 3G and 4G LTE PowerSmart devices. According to the company, the platforms are targeted at multimode, multiband applications such as smartphones, tablets and other data-centric mobile broadband devices.

The products include PowerSmart 4G that the company said is a converged power platform capable of up to 12 bands of 4G LTE, 3G and 2G. It is designed for 4G/LTE operation and expands RFMD's first-generation PowerSmart power platform by adding three bands of 3G or 4G/LTE coverage. PowerSmart 4G also includes all necessary switch and signal conditioning functionality in a compact reference design, noted the RFMD.

RFMD's expanded PowerSmart product family also includes a power platform optimized for emerging 3G entry (3Ge) applications capable of coverage of up to seven bands of 3G or 2G. Similar to PowerSmart 4G, RFMD's PowerSmart power platform for emerging 3Ge applications includes all necessary switch and signal conditioning functionality in a compact reference design.

Likewise, RFMD is expanding the PowerSmart product family to include multiple 3G and 4G discrete power amplifiers (PAs). The discrete PAs can be placed optionally with any RFMD PowerSmart power platform to achieve additional band or mode coverage. Architected in tandem with the RF Configurable Power Core in each PowerSmart power platform, these discrete PAs can deliver significantly improved PA efficiency at backed-off power, claimed the company.

RFMD offers a broad portfolio of 3G and 4G LTE solutions in single-mode and converged architectures to ensure compatibility with leading chipset providers and enable global platform manufacturing. RFMD's 3G and 4G LTE product portfolio reduces the thermal impact of data usage in smartphones while enabling increased battery life during data-centric applications such as web surfing, video calls and internet radio services, added the firm.
