SPECIFICATION Part No. : ALA.01.07.0095A Product Name : 1575MHz GPS-GALILEO Ceramic Active Loop Module Features : 16dB One Stage GPS/GALILEO PCB Dims: 45*10*2.3mmmm RoHS Compliant SPE-12-8-036/B/WY Page 1 of 15 1. Introduction The active loop antenna ALA.01 is best suited for applications where omni-directionality is important. The average gain is similar to an 18mm active patch antenna but in a much narrower profile, only 2.3mm at its highest point, allowing this antenna to be used perpendicular to the device main-board, or placed adjacent to the top or bottom of device main board. A one stage LNA combined with a SAW filter boosts the S/N (C/N) of the GPS/GALILEO system and helps to overcome some noise effects from todays crowded device boards that passive antennas cannot resolve. The antenna can be placed in a plastic slot in the device housing. Alternatively, adhesive foam, hot-melt, or non-conductive screws could be used to mount the antenna. The core antenna design principle of loop current flow tends to lock-out a lot of surface noise from close circuitry from entering the antenna. SPE-12-8-036/B/WY Page 2 of 15
