Overview
The u-blox 6 leadless chip carrier (LCC) modules are standalone GPS and GPS/GLONASS/QZSS
1
modules featuring
the high performance u-blox
-
6 positioning engine. These compact, easy to integrate modules combine
exceptional GPS performance with highly flexible power, design, and connectivity options. Their compact form
factors and SMT pads allow fully automated assembly with standard pick & place and reflow-soldering
equipment for cost-efficient, high-volume production enabling short time-to-market.
u-blox positioning modules are not designed for life saving or supporting devices or for aviation and should not
be used in products that could in any way negatively impact the security or health of the user or third parties or
that could cause damage to goods.

Architecture
u-blox 6 LCC modules consist of two functional parts - the RF and the Baseband sections. See
for block
diagrams of the modules.
The RF Front-End includes the input matching elements, the SAW bandpass filter, the u-blox 6 RF-IC (with
integrated LNA) and the frequency source.
The Baseband section contains the u-blox 6 Baseband processor, the RTC crystal and additional elements such as
the optional FLASH Memory for enhanced programmability and flexibility.
