Mediatek has released a five-in-one combo wireless system-on-a-chip (SOC), with multi-system GNSS, to support full featured smartphones, tablets, and other premium mobile devices.

The MT6630 dramatically reduces the component count and eBOM while improving ease-of-design for manufacturers by eliminating external low noise amplifiers and integrating the Wi-Fi 2.4 GHz and 5 GHz power amplifiers, Bluetooth power amplifiers, and transmit-receive (T/R) switch into a PCBA footprint less than 65 square millimeters.

Features include:

  • Concurrent tri-band reception of GPS, GLONASS, Beidou, Galileo, and QZSS with industry leading sensitivity, low power, positioning accuracy, and the longest prediction engine
  • Dual-band single-stream 802.11a/b/g/n/ac with 20/40/80MHz channel bandwidth
  • 802.11v time of flight protocol support and management engines to enable higher accuracy of indoor positioning via Wi-Fi
  • Advanced support for Wi-Fi Direct Services and Miracast optimization for easier pairing, increased robustness, advanced use-cases, and lower power
  • Bluetooth 4.1 with Classic, High-Speed and Low-Energy support, and ANT+ for compatibility with the latest fitness tracking, health monitoring, and point of information devices and applications
  • FM transceiver with RDS/RBDS
  • Integrated engines and algorithms for full concurrent operation and co-existence, including industry-leading throughput during LTE transmission
  • The MT6630 delivers full concurrent operation of all 5 systems operating at maximum compute intensity with no degradation compared to single-system operation while offloading the mobile device CPU for design ease and extended battery life.

As a focus on low power and digital home convergence, the MT6630 uses a configurable PA architecture to save current at commonly used power levels, including those used for Miracast Wi-Fi Direct services. The MT6630 implements advanced co-existence techniques, including for LTE to deliver industry-leading throughputs. The MT6630 also supports Wi-Fi diversity for premium smartphones and tablets to improve antenna angle sensitivity and handheld scenarios.

“The MT6630 makes it simple for manufacturers to bring mobile devices to market with sophisticated wireless features, lower power and uncompromised performance,” said SR Tsai, general manager of MediaTek’s Connectivity Business Unit. “The MT6630 furthers MediaTek’s focus to deliver the best experiences across the digital home and mobile applications by using its unique leadership position in digital TV host processors, smartphone platforms, and connectivity.”

The small-footprint design is available in 5 x 5-mm wafer-level chip-scale package (WLCSP) or a 7 x 7 mm quad flat no-leads (QFN) and requires only 44 components, which is around half that of other integrated wireless solutions, the company said.

Mediatek’s MT6630 is sampling now and complements the recently announced MT6595 octa-core SOC with LTE for premium mobile devices. The first commercially available devices to use the MT6630 are expected in the second half of 2014.
