RF & Wireless SiP for

RF & Wireless SiP for Cellular IoT, Bluetooth 5, Thread, and Zigbee Fully Integrated L1/L2 RTK Solution for Centimeter- Level Positioning Applications u-blox has announced the results of its collaboration with Korean broadcast media company MBC. With assistance from u-blox, MBC has launched an ultra-compact L1/L2 real time kinematic (RTK) multi-band device, the MBC MRP-2000, featuring a u-blox ZED-F9P high precision GNSS module. The solution is the first to offer the Korean market a GNSS RTK receiver and wireless access to a GNSS correction service in a single box. To achieve centimeter-level position accuracy, high precision GNSS receivers combine multi-band satellite signal reception and GNSS correction data. In addition to mitigating positioning errors incurred as the satellite signals cross the ionosphere, multi-band reception significantly speeds up the time it takes the receiver to determine its location. The ZED-F9P process GNSS correction data, received via a wireless data connection, using integrated RTK algorithms. For uninterrupted centimeter-level accuracy, it requires constant data access over the air. Weighing just 50 g, the compact and extremely low power MRP-2000 provides centimeter-level positioning accuracy for a wide range of portable and mobile applications such as autonomous vehicles, drones, and survey equipment. It comes with a subscription to MBC’s RTK correction service, delivered nation wide using digital media broadcasting (DMB) networks, with LTE fallback. The u-blox ZEDF9P GNSS receiver featured in the MRP-2000 keeps the cost, size, and power consumption of the solution low. With advanced multiband RTK algorithms integrated on the chip, MBC was able to enable centimeter-level positioning with no additional hardware or third party RTK libraries, cutting the time it took to bring the solution to market. ■ ublox www.u-blox.com Nordic Semiconductor ASA demonstrated its newly-launched nRF9160 System-in- Package (SiP), an LTE-M/NB-IoT cellular IoT solution, at International CES 2019. Nordic also demonstrated its nRF52840 multiprotocol System-on-Chip (SoC), together with its other nRF52 SoCs. The recent launch of the nRF9160 SiP makes cellular IoT wireless technology accessible to any application because of the unique ease with which the product can be designed-in. At just 10 x 16 x 1 mm, the nRF9160 SiP is suitable for even compact wearable consumer and medical devices yet is a complete solution that integrates everything a cellular connection and IoT application needs (except battery, SIM, and antenna). The product has received GCF certification along with separately required FCC and CE regulatory certifications. Nordic partnered with Qorvo to make a SiP that more closely resembles an integrated chip than a conventional module. The nRF9160 SiP leverages Qorvo’s stateof-the-art, proven RF front-end, advanced packaging, and MicroShield technology to deliver a unique, ultra-compact solution that combines high performance with low power consumption. The nRF9160 SiP supports global operation with a single SiP variant thanks to the combination of Nordic’s multimode LTE-M/NB-IoT modem, SAW-less transceiver, and the custom RF front-end solution from Qorvo. The nRF9160 SiP provides LTE-M and NB-IoT support in the 700 MHz to 2.2 GHz spectrum allocation and incorporates Arm’s latest Arm Cortex M-33 CPU core, Arm TrustZone, and Arm CryptoCell security for Internet-level encryption and application protection. The SiP features 1 MB Flash plus 256 kB RAM and a broad range peripheral set, analog and digital interfaces, 32 GPIOs, a stand-alone modem with full LTE capability, plus a multiband RF frontend. In addition, the SiP uniquely features built-in support for positioning via an integrated Assisted GPS (A-GPS). The nRF9160 SiP demonstration will illustrate the ease with which the cellular IoT product can be designed-in to asset-tracking applications. The demonstration will be based on an nRF9160 Development Kit (DK) and will link, using LTE-M wireless connectivity, to Nordic’s ‘nRF Connect for Cloud’, the company’s versatile IoT connectivity enabler. A second demonstration used the nRF9160 DK with LTE-M and nRF Connect for Cloud but this time will show how the DK’s builtin nRF52840 SoC can be used to extend a cellular IoT link to a Bluetooth LE device as the foundation of a real application. This demonstration shows how, for example, moisture sensors on a farm could connect via Bluetooth 5 (or Thread or Zigbee) to a gateway equipped with an nRF52840 SoC with the data then relayed via a cellular IoT device to the Cloud for analysis. ■ Nordic Semiconductor ASA www.nordicsemi.com 3 W C-Band GaN PA Module offers Doherty Efficiency RFMW, Ltd. announced design and sales support for a GaN power amplifier module (PAM).
