Quantance Showcases its Q845 qBoost ET Power Supply at Mobile World Congress

By Nathesh, TMCnet Contributor

Quantance, a manufacturer of 4G/LTE (News - Alert) envelope tracking (ET) power supplies, will be demonstrating its Q845 qBoost ET Power Supply as an integrated solution within Fujitsu’s MB86L11 2G/3G/4G Transceiver reference design platform, at Mobile World Congress (News - Alert) in Barcelona, February 25-28.

Featuring Quantance Q845 ET Power Supply and the Fujitsu MB86L11 multimode transceiver, the demonstrations at MWC will supposedly reveal enhancements in system level improvements in RF power amplifier (PA) efficiency and peak linear PA power, outperforming Average Power Tracking (APT) solutions.

According to Quantance (News - Alert), the Q845 ET power supply is the third-generation product implementation of qBoost technology, specifically targeted for envelope tracking in smartphones, tablets, data cards and other mobile devices featuring high-speed data. Designed for low cost and integration simplicity, the Q845 is a tiny, single chip solution in a wafer level, and while it is optimized as an ET power supply, it can also be provisioned in real time to operate in three modes: ET, APT and bypass.  

Fujitsu’s (News - Alert) MB86L11 is reportedly a single chip multiband, multimode transceiver, supporting all wireless communication modes including LTE (FDD & TDD), HSPA+, DC-HSPA, WCDMA, GSM, EDGE, CDMA and TD-SCDMA. The MB86L11 transceiver also incorporates many advanced features, including envelope tracking (ET) and antenna tuning (AT).

The company asserted that its ICs deliver low power consumption, a small footprint and a highly flexible API to bring down the total cost and integration effort.

Vikas Vinayak, CEO at Quantance remarked, “This ET product demonstration shows that our industry-leading performance and ability to meet all 3GPP noise requirements can be maintained in a compact smartphone form factor, using aggressive design rules, mass market components, the standard MIPI interface and Fujitsu’s commercial transceiver to drive the ET system. We think this clearly confirms ET is ready for mass-market adoption and that both Fujitsu and Quantance are in a leadership role, poised for a quick roll out of qBoost ET solutions in smartphones, tablets and other mobile devices.”
