UC430 antenna module - NEW
• Smallest antenna module in the world
• Small chip antenna with ground plane = GPS antenna
• Performance depending on the size of the ground plane
• With 80mm wide ground plane, performance close to 18x18 patch
antenna
• Fits perfectly to digital cameras and navigator type applications
• Flexible orientation of tracking device inside a vehicle
• Circular radiation pattern
• Ultra low power consumption with advanced power save modes
• External antenna connectivity enables usage as back-up antenna
when external antenna is primarily used

UC430 antenna module - NEW
• Features and Sales arguments
• Low power consumption
• Battery operated devices last longer with smaller batteries which are cheaper
• Advanced power saving modes, only 125uA with SiRF Aware
• Embedded CGEE – 3 days internally calculated AGPS allows fast TTFF
• Chip antenna
• Minimal compromize in performance, comparable to 18x18 patch antenna
• Less sensitive to orientation than a patch antenna
• Most difficult part already designed in by Fastrax, which allows faster design cycles and
shorter Time To Market
• Small size
• UC430 is same size as most other GPS modules without antenna
• Allows very thin designs compared to patch antennas
• Circuitry for optional external antenna
• Embedded chip antenna can also be used as back-up antenna if external antenna is
removed
11
• SMT module
CONFIDENTIAL – DO NOT DISTRIBUTE
• Cheaper manufacturing
as no manual manufacturing is needed
