Fujitsu Semiconductor Intros LTE FDD TDD Transceiver

Fujitsu Semiconductor Wireless introduced an LTE FDD and TDD optimized transceiver. The Fujitsu design eliminates the need for external low noise amplifiers (LNAs) and inter-stage surface acoustic wave (SAW) filters.

The new device (MB86L13A), which covers the frequency spectrum from 700 to 2700 MHz, offers multiple transmit, receive and diversity ports. The device offers the flexibility to map ports and bands for roaming requirements. The transceiver uses an open standard MIPI DigRF 4G v1.1Rev0.06 interface to the baseband. The device supports all global FDD bands 1-21, 23-25, and TDD bands 33-41. The MB86L13A supports all LTE bandwidths up to 20MHz. Future transceivers on the roadmap for this year include a 3GPP Release 10-compliant, single RFIC solution.

The device is sampling now and will be available in volume Q2 2012.

"The MB86L13A can speed time to market for baseband providers looking to add robust LTE capabilities to their existing 2G/3G solution," said Vivek Bhan, vice president, Fujitsu Semiconductor Wireless Products. "The new device provides multiband LTE support on a single IC, complementing the 2G/3G-only solutions offered by platform partners for the growing LTE market."

  • In February, Fujitsu introduced the MB86L11A 2G/3G/4G multimode, multiband SAW-less transceiver with several advanced transmit features, including enhanced power control, envelope tracking, and antenna tuning.

  • In 2009, Fujitsu began shipping the industry's first SAW-less transceiver for 2G/3G networks.

  • In 2010, Fujitsu introduced the first 3G and LTE SAW-less transceiver, which has been integrated into dongles, tablets and multimode 2G/3G/4G smartphones.
