U-blox is introducing a new module designed to speed time to market for system developers of GNSS applications who have limited experience in RF and antenna design. The SAM-M8Q GNSS receiver with integrated antenna is housed in a tiny 15.5 by 15.5 by 6.3 millimeter package. It can be easily embedded in small devices that require location information, such as asset tracking and telematics systems, and generic automotive after-market applications, u-blox said. By using the latest u-blox M8 multi-GNSS receiver technology, the module is able to offer simultaneous reception of GPS, GLONASS, and Galileo satellite signals. Ultra-compact SAM-M8Q module. The combination of an integrated wide-band antenna along with the module’s SAW filter and low-noise amplifier (LNA)architecture ensures that the SAM-M8Q receiver delivers robust performance in the presence of high frequency signals from other electronic equipment, such as cellular modems, which can cause interference. “The SAM-M8Q is intended for customers who don’t have much experience in RF and antenna design,” said Kim Kaisti, Director, Product Management, Product Center Positioning. He added, “It is aimed at applications that require an embedded antenna and where the surface mount package allows for easier assembly and installation in the end-equipment.” Samples of the SAM-M8Q will be available in mid-January 2017. The modules will be in full production in mid-February 2017.
