ASGGB184.A – Active GNSS Surface Mount 18mm Patch


Active GNSS Surface Mount 18mm Patch

The Taoglas ASGGB184.A is a single band active GNSS patch covering GPS/GLONASS/BeiDou/Galileo. With hidden active circuitry embedded between the ceramic patch and PCB base, it has been designed to allow the user to mount it directly onto their device PCB. This eliminates the need for using a cable and connector thus speeding up the assembly process by allowing successfully solder surface mount components to a circuit board via the SMD process. The ASGGB184 measures just 18 x 18 x 6.45mm and is optimized for a ground plane size of 70*70mm being required for operation however smaller ground planes can be used.

The ASGGB184 also includes a two-stage LNA and a front-end SAW filter to reduce out of band noise such as from nearby cellular transceivers and this improves the probability of the wireless device passing radiated spurious emissions certification. As with many high performance Taoglas patches, the ASGGB series is produced in a TS16949 automotive quality approved facility and each patch produced is 100% tested for gain (S21) and return loss (S11) to ensure total consistency of performance. If the user device can accommodate it, a larger patch, the 25x25mm ASGGB254.A is also available with better performance figures.

Typical applications include:
• Navigation
• Commercial Transportation
• Asset Tracking

Taoglas also offers custom tuning service based on minimum order quantities, contact your regional Taoglas customer support team for further information.
