UBX-G0011 RF Front-end for Capture & Process

The UBX-G0011 is a highly integrated RF front-end IC providing high performance and low power operation dedicated to supporting u-blox’ Capture and Process technology. Capture & Process enables a wide range of instant location capture and ultra low power applications such as photo-geotagging and long-life location loggers.

The digitized output is available in a serialized data stream to facilitate software signal processing. The highly-integrated PLL synthesizer of the UBX-G0011 requires only two passive components to implement an off-chip loop filter.

Highlights

  • Optimized for lowest possible power consumption: only active for a fraction of a second per capture
  • Part of u-blox' patented Capture & Process technology for instantaneous, low-power position capture
  • Designed to collect raw GPS satellite data which can be processed for a location fix later by u-blox' YUMA software and service
  • Very low external component count
  • Ultra small package:
    • QT: 24-pin MLF package, 4 x 4 x 0.9 mm, 
    • CT: 46 pad CSP, 2.2 x 2.2 x 0.35 mm
