Giant Microelectronics Introduces World's Smallest and Lowest Power UWB SoC for Precise Ranging, Positioning and Wireless Applications


Shenzhen Giant Microelectronics Company Limited (GiantSemi), a global supplier of wireless SoC (system-on-chip), today announced an industry-leading GT1500 UWB (ultra-wideband) SoC for ranging, positioning and wireless connectivity applications.

UWB technology enables ubiquitous fast and accurate ranging and positioning capabilities either indoors or outdoors, independent of networking infrastructure coverage. In addition to its superb ranging capability, UWB provides energy-efficient wireless connectivity at configurable data rates, creating new use cases with mobile phones, wearable devices, digital keys, tags and trackers; enabling new consumer-oriented and commercial applications in areas such as access control, smart payments, smart homes and smart cities.

Leading the industry in lowest power consumption and overall performance, GiantSemi's GT1500 is the world's smallest UWB single-chip SoC housed in a low profile package requiring minimal footprint of 9mm2. GT1500 is a single-chip standard platform UWB solution comprises of four receiver channels - combining RF, analog and baseband functions, tightly integrated with an embedded MCU to perform control and protocols processing, all in a single device.

GT1500 is ideally suited for space-constrained wearable and IoT product applications. It significantly reduces 3D AoA design complexity, component counts and the product BoM costs. This compact device allows close antenna placement, thus improving signal reception and overall UWB performance. In addition, GT1500 prolongs the battery life of an UWB always-on tag as compare to similar products operating with a 235mAh battery such as CR2032. The longer-lasting battery life of GT1500 significantly enhances user experiences for UWB always-on applications.



GT1500 has been certified by the FiRa Consortium, it complies with the Car Connectivity Consortium (CCC) Digital Key Release 3.0 as well.

GT1500 highlights:


  • Low profile wafer level package: 49pin, 3.2mm (L) x 2.8mm (W), 0.6mm (H) thickness
  • 1T4R: one transmitter and four receivers
  • Protocol processing on-chip
  • Single-sided and double-sided TWR (Two-Way Ranging)
  • 2D/3D AoA measurement and TDoA (Time Difference of Arrival)
  • Frequency range: 4.0 ~ 9.0GHz
  • Data rates: 31.2Mbps, 27.2Mbps, 7.8Mbps, 6.8Mbps, 850Kbps
  • Standard interfaces: SPI, I2C, UART, GPIO
  • Ranging accuracy: ±3cm, AoA accuracy: ±3°
  • Peak power consumption of receivers: 125mW
  • Peak power consumption of transmitter: 69mW

GiantSemi will showcase GT1500 in Mobile World Congress (MWC) Barcelona 2024 on 26 - 29 February, the booth number is 2A64MR in Hall 2. Together, GiantSemi's partners will also showcase industry-leading UWB applications including:

  • UWB tag featuring longer-lasting life using coin battery CR2032
  • Downlink TDoA (DL-TDoA) featuring easy installation and supporting scalable unlimited tag number, operating on UWB channel 3, 5 and 9
  • UWB lossless wireless audio featuring data rate up to 10Mbps.

GT1500 enables much faster time to market with excellent performance, quality and cost effectiveness, volume shipment is immediately available now. For additional information about GT1500 and GiantSemi, visit www.giantsemi.com or contact us at [email protected].
